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.

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.
