realmin - Smallest positive normalized floating-point number
Syntax
n = realmin
Description
n = realmin returns the smallest
positive normalized floating-point number on your computer. Anything smaller
underflows or is an IEEE "denormal."
REALMIN('double') is the same as REALMIN with
no arguments.
REALMIN('single') is the smallest positive normalized
single precision floating point number on your computer.
Examples
realmin is 2^(-1022) or about 2.2251e-308.
Algorithm
The realmin function is equivalent to pow2(1,minexp) where minexp is
the smallest possible floating-point exponent.
Execute type realmin to see minexp for
various computers.
