NAME
       logb(), logbf(), logbl(), logbw(), logbq() - radix-independent exponent
       functions

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       The function computes the exponent of the floating point value x.  For‐
       mally,  the return value is the integral part of log base r of |x| as a
       signed floating point value, for nonzero x, where r is the radix of the
       machine's  floating-point  arithmetic.	The radix r is 2 on HP-UX sys‐
       tems.

       If x is denormal, it is treated as though it  were  normalized,	before
       the exponent is determined.

       is an version of it takes an 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

       Make sure your program includes Link in the math library by  specifying
       on  the compiler or linker command line.	 For more information, see the
       at the following site:

RETURN VALUE
       Upon successful completion, returns the exponent of x.

       If x is NaN, returns NaN.

       If x returns +INFINITY.

       If x is zero, returns (equal to −INFINITY) and  raises  the  divide-by-
       zero floating-point exception.

ERRORS
       If x is zero, sets to [EDOM].

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