NAG C Library Function Document

nag_real_smallest_number (X02AKC) returns the smallest positive number in the model of floating-point arithmetic described in the x02 Chapter Introduction. The returned value is equal to

b^{e_{\min} - 1}

, where

b

is the arithmetic base (see nag_real_base (X02BHC)) and

e_{\min}

is the minimum exponent (see nag_real_min_exponent (X02BKC)) in the model.
