BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

kldexp - computes x * 2**n

LIBRARY CALL

double kldexp(
double x,
int n)

INPUT

OUTPUT

none

RETURN VALUE

the double precision value x * 2**n

DESCRIPTION

The kldexp function computes x * 2**n by performing exponent manipulation rather than multiplication.

This is provided in all POSIX and X/OPEN compliant C math libraries. Currently kldexp is simply a macro to ldexp because Khoros does not run on any machine whose math library does not include this function. If Khoros is ported to a machine without this function then a replacement will be written.
