NAME

       isnormal() - floating-point test for normalized value

SYNOPSIS

       floating-type

DESCRIPTION

       The  macro  determines whether its argument is a normalized value (neither zero, denormalized, infinite, nor 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  floating  type.
       For PA-RISC, the argument must be either or

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 normalized value.  The macro raises no floating-point exceptions.

ERRORS

       No errors are defined.

EXAMPLES

       Make sure a value is normalized before continuing operations on it:
