scalbn(3M)

NAME

     scalbn - load exponent of a radix-independent floating-point
     number

SYNOPSIS

     cc [ flag ... ] file ... -lm [ library ... ]
     #include <math.h>

     double scalbn(double x, int n);

DESCRIPTION

     The scalbn() function computes x * r**n ,  where  r  is  the
     radix of the machine's floating point arithmetic.

RETURN VALUES

     Upon successful completion, the scalbn() function returns  x
     * r**n.

     If  the  correct  value  would  overflow,  scalbn()  returns
     _HUGE_VAL (according to the sign of x).

     The scalbn() function returns x when x is _Inf.

     If x is NaN, then scalbn() returns NaN.
