NAME
       isfinite() - floating-point finiteness macro

SYNOPSIS
       floating-type

DESCRIPTION
       The  macro  determines  whether	its argument has a finite value (zero,
       denormalized, or normalized, and not infinite or	 NaN).	 The  argument
       must  be	 of  floating type, and classification is based on the type of
       the argument.  For HP Integrity servers, the argument can be any floatā€
       ing type.  For PA-RISC, the argument must be either or

       The  macro  implements  the  functionality  recommended by the IEEE-754
       standard for floating-point arithmetic.

USAGE
       To use the macro, compile either with the default option	 or  with  the
       and  options.  Make sure your program includes Link in the math library
       by specifying on the compiler or linker command line.

RETURN VALUE
       The macro returns a nonzero value if and only if	 its  argument	has  a
       finite value.  The macro raises no floating-point exceptions.

ERRORS
       No errors are defined.

EXAMPLES
       Make sure a value is finite before continuing operations on it:
