Decimal part

To multiply numbers in scientific notation, multiply the decimal parts of the numbers and add the powers of 10 ... 

When raising a number in scientific notation to a particular power raise the decimal part of the number to the power and multiply the power of 10 by the power ... 

The standard rule for rounding numbers is to round down when the fractional or decimal part is less than half (when the remainder is less than half of the divisor), round up when the fractional part is more than half, and round to the closer even number when the fractional part is exactly half. 

A logarithm is composed of a characteristic and a mantissa. The characteristic is the integer part and the mantissa is the decimal part ... 

If you simplify by using a log table, then the decimal part of this exponent (-4.30) must fjTftt MiRteilfl. 7t)Hfr[Pg.345]

A series of digits to the right of the decimal point specify the fractional (or decimal) part of the number (tenths, hundredths, thousandths, etc.). 

Rounding up or rounding down the decimal part of a number to a given number of decimal places is achieved by some generally accepted rules. The number is first truncated to the required number of decimal places, in the manner described above attention is then focused on the tail (see above) ... 

To make the mantissa positive, subtract 1 from the integral part and add 1 to the decimal part, Thus,... 

Notice that the decimal part of our answer (the digits to the right of the decimal point) is the same as the decimal part of the minuend. That will always be true when we subtract a whole number from a number with a decimal part. In fact, you can bring the decimal part of the minuend right into your answer and just handle the subtraction of the whole number parts. 

If the value of the equilibrium generalised enter coefficient Ee is determined from experimental data about interfacial and surface tension, its values are usually close to zero (of the order of decimal parts of mN m 1), the error being 0.3 mN m 1 [541]. As mentioned in [51], since Ee and se are not very accurate, they cannot be employed to predict the penetration of oil drops from the aqueous films onto the interface.

The two parts of the resulting logarithms are called the mantissa and the characteristic. The mantissa is the decimal part, and the characteristic, the integral part. Since tables of logarithms show positive mantissas only, a logarithm such as -5.8111 must be converted to 0.1889-6 before... 

Times are represented by the decimal part of the serial number. You can use either number formatting or worksheet functions to convert these date serial values into comprehensible dates. 

Use MOD(number,1) to return the decimal part of a floating-point number. Example =MOD(2.3333,2) returns 0.3333. =MOD(2.3333,3) returns... 

The integer part of the serial number represents the day, month and year the decimal part represents the time. NOW is recalculated whenever the sheet is recalculated. 

Here, the decimal parts of the numbers are divided the exponent in the denominator is subtracted from that in the numerator. For example. 

Addition or subtraction in scientific notation requires that aU numbers be expressed to a common power of 10. The decimal parts are then added or subtracted, as appropriate. Thus,... 

A floating point number is represented by a sequence of digit characters, possibly preceded by a plus or minus and followed by a decimal part, or an exponent part, or a decimal part followed by an exponent part. Examples are... 

How about significant figures Two significant figures in the mantissa (the decimal part) of the logarithm correspond to two significant figures in the number 4.2 X 10 . ... 

Note that int is a mathematical function that truncates the decimal part of a value and retains only the integer part. 

Science has constantly pushed the boundaries of the very large and the very small. We can, for example, now measure time periods as short as 0.000000000000001 seconds and distances as great as 14,000,000,000 light-years. Because the many zeros in these numbers are cumbersome to write, scientists use scientific notation to write them more compactly In scientific notation, 0.000000000000001 is 1 X 10 and 14,000,000,000 is 1.4 X 10. A number written in scientific notation consists of a decimal part, a number that is usually between 1 and 10, and an exponential part, 10 raised to an exponent, n. 

To convert a number to scientific notation, move the decimal point (either to the left or to the right, as needed) to obtain a number between 1 and 10 and then multiply that number (the decimal part) by 10 raised to the power that reflects the movement of the decimal point. For example, to write 5983 in scientific notation, move the decimal point to the left three places to get 5.983 (a number between 1 and 10) and then multiply the decimal part by 1000 to compensate for moving the decimal point.
