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);

These routines return x, Ns, *(2**, Ns, Fa, n) computed by exponent manipulation.

These routines conform to ISO/IEC 9899:1999 ("ISO C99"), and they implement the Scalb function recommended by -ieee754.

The scalbn() and scalbnf() functions appeared in BSD 4.3 and FreeBSD 2.0, respectively. The scalbln() and scalblnf() functions first appeared in FreeBSD 5.3, and scalblnl() and scalbln() in FreeBSD 6.0 .
