Float data type

The Variant data type is the default data type in VBA. Like Excel itself, the Variant data type handles and interconverts between many different kinds of data integer, floating point, string, etc. The Variant data type automatically chooses the most compact representation. But if your procedure deals with only one kind of data, it will be more efficient and usually faster to declare the variables as, for example. Integer. 

You can also specify the data type of the return value. If none is specified, the Variant data type will be returned. In the example of the preceding section, MolWt returns a floating-point result. The Variant data type is satisfactory ... 

The internal representation of data is not entirely unimportant. When the float data type is used, the data are typically converted to the internal floating-point representation used by the computer on which the RDBMS is installed. This may have unintended consequences because of the rounding that occurs, especially if several mathematical operations are... 

Standard SQL data types, such as integers, float, and text, are useful for storing scientific data, such as counts, measurements, and names. 

Since the range data type is not a standard SQL data type, the standard SQL operators cannot be used with this data type. However, new operators can be defined using SQL functions. Since the range data type is so similar to the float data type, implicit conversion to float is appropriate. This automatically allows many of the standard SQL operators to work with exact(=) range values. 

As with the range text conversion, the range float conversion allows range values to be converted to float, whenever possible. This makes the following SQL work without explicit definition of the sqrt function for range data types. 

In order to properly compare range values it is necessary to define functions that operate directly on the range data type, rather than indirectly after the implicit conversion to float. The following functions define how two range values should be compared for equality, less than, greater than, etc. 

Another important aspect of objects is the methods that operate on them. An ORDBMS calls these functions, but the effect is the same. As shown in this chapter, the functions defined for new data types enable them to be integrated in the SQL language and handled just like standard SQL data types. This can be by casting the data type, for example, to allow range data to be treated as float. New functions that operate exclusively on range data can be defined, such as range cmp. The ability to define operators of new data types enhances their usability and integration into SQL even more. 

Each set of experimental data will likely have to be considered separately. Some measurements may require several columns, while other will require only one. Some measurements may have measured or estimated uncertainties, while others may be more indefinite, such as "active" or "inactive." All measurements will have a date associated with them and this should be stored. Many experimental values will be noninteger numbers. These may be stored using the numeric data type or float or double, depending on the accuracy needed and whether computations on these values will be carried... 

Perl can deal with an astonishing number of data types, including but not limited to text, integers, floating point numbers, complex numbers, and binary numbers. 

Data types treated by MADCAP include real numbers (no distinction is made between floating-point and integer), complex numbers, character strings, matrices with real elements, sets of natural numbers, and arrays of arbitrary elements (77). Notation and facilities exist for character-string manipulation matrix operations of addition, subtraction, multiplication, inversion, and transposition set-theoretic operations of complementation, union, intersection, subtraction, and symmetric subtraction (exclusive or). When the set-theoretic operations were added to the language, set-theoretic comparators for use in conditional expressions and other language extensions to facilitate the programming of combinatorial calculations were incorporated, as well (78). 

It should be kept in mind that the format command does not affect how MATLAB computations are done. Computations on float variables, namely, single or double, are done in appropriate floating point precision, no matter how those variables are displayed. Computations on integer variables are done natively in integer. MATLAB uses double-precision floating point arithmetic, which is accurate to approximately 15 digits and can work with the following data types tTable 1.21. 

Memory allocation/deallocation is automatically managed by LabVIEW. Similar to most programming languages, LabVIEW supports all common data types such as integers, floats, strings, and clusters (structures) and can readily interface with external libraries, Active X components, and NET framework. 

Recent reports on biosorbents based on diverse types of macrophytes are found widely in the literature. Free-floating aquatic plants from the genera Salvinia, Azolla, Eichhornia, Lemna, and Pistia have been described the most. S. natans biomass was able to uptake As(V) at low initial concentrations from 0.25 to 2 mg/L (74.8% and 54%, respectively). The experimental data fitted well to both Langmuir and Freundlich isotherms. The effect of pH and biomass quantities on sorption rate has also been investigated along with some metabolic parameters.105... 

Data management in RS/1 is based on two-dimensional tables. Each cell of a table can contain data representing fixed or floating point numbers, dates, times, or free text. Cells in a particular column are not all constrained to the same type it is possible, for example, to include a note about some missing data in a column of numerical results. A user can work with many hundreds of tables. Tables are based on disk files, accessed through a kind of paging scheme, so there is no limit on table size. Some users work with tables containing hundreds of columns and tens of thousands of rows. 

The data from Figure 25.1 indicate that ilmenite can be recovered at a wide pH range. There is, however, a difference in the floatability of ilmenite from different ore types. Ilmenite can be successfully floated using fatty acid tall oil collectors at alkaline pH or with sodium alkyl sulphate (Ci6H330S03Na) at acidic pH. Figure 25.2 shows the effect of pH on ilmenite flotation from a sand deposit using alkyl sulphate collector. 

JM Mine was moored, pear-shaped, contact mine which had no horns. The jolt received by the pendulum firing mechanism, when a ship struck the mine, closed an electrical contact and fired the detonator. - The mine was filled with ca 110 lbs of a HE ( ) (pp 44-45, Fig 18) Pomegranate Mine was a Vickers antenna mine purchased before WWII. It was spherical, 41 inches in diam, with six chemical horns on the upper hemisphere and two addnl ones welded to the lower hemisphere. An upper antenna and float and/or lower antenna were secured to the mine. No data for HE filler (pp 44 45, Fig 19) Type 3 Mine was the first Japanese attempt to use influence mines, copied from German S Mine. Their cylindrical A1 cases were either 7 or 11 feet long and 21 inches in diam. No data for HE used and the description of the mine given in Ref 1, p 46 is hard to understand Mark 2 Mod 1 Explosive Hook was actually a device for mine sweeping rather than a mine.
