critical impact:

drem, dremf, dreml - not supported; temporarily available (CrUn41)

Problem description

The drem, dremf, and dreml routines exist on Tru64 UNIX, but not on HP-UX. These routines will be temporarily available in the Tru64 UNIX Migration Environment for HP-UX.

The drem, dremf, and dreml routines compute the floating-point remainder.

The Migration Environment contains Tru64 UNIX APIs, development tools, and commands and utilities to assist customers in migrating their applications from Tru64 UNIX to HP-UX.

Solution description

The drem, dremf, and dreml routine functionality is similar to functionality of the remainder, remainderf, and remainderl routines on both HP-UX and Tru64 UNIX.

Monitor HP-UX release notes in future releases for information about drem, dremf, and dreml availability.

The following example shows how the drem, dremf, and dreml routines can be replaced with the remainder, remainderf, and remainderl routines:

double
drem (double x, double y) {

        return remainder (x, y);

}


float
dremf (float x, float y) {

        return remainderf (x, y);
}



long double
dreml (long double x, long double y) {

        return remainderl (x, y);
}        

Please note that the Migration Environment is temporary.
