     by radix

SYNOPSIS
     #include <math.h>

     double
     scalbln(double x, long n);

     float
     scalblnf(float x, long n);

     long double
     scalblnl(long double x, long n);

     double
     scalbn(double x, int n);

     float
     scalbnf(float x, int n);

     long double
     scalbnl(long double x, int n);

DESCRIPTION
     scalbln() and scalbn() return x*(2**n) computed by exponent manipulation.
     The scalblnf() and scalbnf() functions are single precision versions of
     scalbln() and scalbn(), respectively.  The scalblnl() and scalbnl()
     functions are extended precision versions of scalbln() and scalbn(),
     respectively.

STANDARDS
     IEEE Std 754-1985

HISTORY
     The scalbln, scalblnf and scalblnl functions appeared in OpenBSD 4.7.
     The scalbn, scalbnf, and scalbnl, functions appeared in 4.3BSD,
     NetBSD 1.1 and OpenBSD 4.5, respectively.
