7.12.6.13 The scalbn and scalbln functions

Synopsis

1

#include <math.h>
double scalbn(double x, int n);
float scalbnf(float x, int n);
long double scalbnl(long double x, int n);
double scalbln(double x, long int n);
float scalblnf(float x, long int n);
long double scalblnl(long double x, long int n);

Description

2

The scalbn and scalbln functions compute x FLT_RADIXⁿ efficiently, not normally by computing FLT_RADIXⁿ explicitly. A range error may occur.

Returns

3

The scalbn and scalbln functions return x FLT_RADIXⁿ .
