HUGE Function

Purpose

Returns the largest positive value allowable for a floating-point variable.

HUGE(x)

x is an expression of type FLOAT BINARY or FLOAT DECIMAL.

HUGE returns a floating-point value that is the largest positive value x can have. It has the base, mode, and precision of x.

The HUGE built-in is not allowed during restricted expression evaluation.

This example shows the IEEE FLOAT BINARY values returned for the HUGE built-in.

dcl d float bin (52);
dcl f float bin (23);

   d = huge(d);    /* 1.7976931348623157E+308 */
   f = huge(f);    /* 3.402823466E+38         */
