NAME
       scalb(), scalbf(), scalbl(), scalbw(), scalbq() - scale exponent of a radix-independent floating-point number

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       The  function  returns  where  r  is  the  radix of the machine's floating-point arithmetic.  The radix r is 2 on all PA-RISC and Integrity
       servers.

   Integrity Server Only
       is a version of it takes arguments and returns a result.

       is a version of it takes arguments and returns a result.

       is an version of it takes arguments 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 y returns x.

       If x is +0 and y is +INFINITY, returns a NaN and raises the invalid exception.

       If x is +0 and y is an integer less than +INFINITY, returns +0.

       If x is +INFINITY and y is an integer greater than -INFINITY, returns +INFINITY.

       If x is finite and positive-signed and y is -INFINITY, returns +0.

       If x is positive and y is +INFINITY, returns +INFINITY.

       If x is +INFINITY and y is -INFINITY, returns a NaN.

       If x or y is NaN, returns a NaN.

       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
       If the correct value would overflow or underflow, sets to [ERANGE].

   Integrity Server Only
       HP-UX functions on Integrity servers do not set by default.  For setting, compile with the option.
