NAME

flmin, flmax, ffrac, dflmin, dflmax, dffrac, inmax − return extreme values

SYNTAX

function flmin() function flmax() function ffrac() double precision function dflmin() double precision function dflmax() double precision function dffrac() function inmax()

DESCRIPTION

The flmin and flmax functions return the minimum and maximum positive floating point values, respectively. The dflmin and dflmax functions return the minimum and maximum positive double precision floating point values. The inmax function returns the maximum positive integer value.

The ffrac and dffrac functions return the fractional accuracy of single and double precision floating point numbers, respectively. This is the difference between 1.0 and the smallest real number greater than 1.0.

These functions can be used by programs that must scale algorithms to the numerical range of the processor.
