Nonzero integers

Nonzero integers. Nonzero integers always count as significant figures. 

If a nonpositive determinant v or Vb occurs in a line search of 5(6), subroutine GRS2 tries a new search point with 9 — 9 half as large. This process is repeated until a positive determinant Vb is obtained for every response block. These precautions ensure a uniform definition of 5(6) during each iteration. GRS2 takes the same action if the user s subroutine MODEL returns a nonzero integer lERR. thus reporting an unsuccessful function evaluation. 

Armchair SWNTs are metals those with n — m = 3k, where k is a nonzero integer, are semiconductors with a tiny band gap and all others are semiconductors with a band gap that inversely depends on the nanotube diameter [8b, 17, 18]. The MWNTs consist of capped concentric cylinders separated by 3.45 A (which is slightly larger than the interlayer spacing in graphite) because the number of carbon atoms increases as we go from an inner cylinder to an outer cylinder and it is not possible to maintain perfect ABAB stacking as in graphite. Thus, an inter-... 

RULE Zeros to the left of the first nonzero integer are not significant they serve only to locate the position of the decimal point. ... 

Such nuclei must have an odd number of unpaired proton (/ = ) spins, and an odd number of unpaired neutron (/ = i) spins, so the net magnetic spin must be a nonzero integer [i.e., an integer multiple of 2( )]. Such nuclei are detectable by NMR. A few common examples are (/ = 1), (/ = 3),...
