NAME

       scalbn(), scalbnf(), scalbnl(), scalbnq(), scalbnw() - scale exponent of a radix-independent floating-point number

SYNOPSIS

   HP Integrity Servers Only
DESCRIPTION

       The  function  returns where r is the radix of the machine's floating-point arithmetic.	When r is 2 (as it is on all PA-RISC and Integrity
       servers), computes the same value as

   Integrity Servers Only
       is a version of it takes a first argument and returns a result.

       is a version of it takes a first argument and returns a result.

       is an version of it takes an first argument and returns an result.

       is equivalent to on HP-UX systems.

USAGE

       To use these functions compile either with the default option or with the and options.

       To use (for Integrity servers) or compile also with the option.

       Make sure your program includes Link in the math library by specifying on the compiler or linker command line.

RETURN VALUE

       and are equivalent.

       If x zero, or a NaN, returns x.

       returns a properly signed infinity in lieu of a value whose magnitude is too large, and raises the overflow and inexact exceptions.

       raises the underflow and inexact exceptions whenever a result is tiny (essentially denormal or zero) and thereby suffers loss of  accuracy,
       and may raise those exceptions if the result is merely tiny.

ERRORS

       No errors are defined.
