SCALBN(3)						   BSD Library Functions Manual 						 SCALBN(3)

NAME
scalbn, scalbnf, scalbnl -- exponent using FLT_RADIX LIBRARY
Math Library (libm, -lm) SYNOPSIS
#include <math.h> double scalbn(double x, int n); float scalbnf(float x, int n); long double scalbnl(long double x, int n); DESCRIPTION
The scalbn(), scalbnf(), and scalbnl() functions compute x * r^n, where r is the radix of the machine's floating point arithmetic, defined by the FLT_RADIX constant in <float.h>. The rationale is efficiency; r^n is not computed explicitly. RETURN VALUES
As described above, upon successful completion, the described functions return the exponent computed using FLT_RADIX. Otherwise the follow- ing may occur: 1. When the result would cause an overflow, a range error occurs and +-HUGE_VAL, +-HUGE_VALF, or +-HUGE_VALL is returned according to the sign of x and the return type of the corresponding function. 2. When the correct value would cause an underflow and it is not representable, a range error occurs and either 0.0 or an implementa- tion-defined value is returned. When an underflow occurs but the correct value is representable, a range error occurs but the correct value is returned. 3. If x is +-0 or +-Inf, x is returned. Likewise, if n is zero, x is returned. If x is NaN, NaN is returned. SEE ALSO
exp(3), frexp(3), ldexp(3), math(3) STANDARDS
The described functions conform to ISO/IEC 9899:1999 (``ISO C99''). BSD
