NAME
       fmad64(), fmad128(), fmad32() - decimal floating multiply-add functions

SYNOPSIS
DESCRIPTION
       The  function  returns (x*y) + z, rounded as one ternary operation:  it computes the value (as if) to infinite precision and rounds once to
       the result format, according to the current (decimal) rounding mode.

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

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

       These math functions are supported for HP-UX 11i Version 3 September 2008 Update and forward.

USAGE
       To use any of these functions, compile with the option.

       Make sure your program defines and then includes

       Link in the math library by specifying or on the linking command line.

       For more information, see the at the following site:

RETURN VALUE
       If x, y, or z is NaN, returns NaN.

       If one of x and y is infinite, the other is zero, and z is not NaN, returns NaN and raises the invalid exception.

       If x times y is an exact infinity and z is also an infinity but with the opposite sign, returns NaN and raises the invalid exception.

       returns the properly signed infinity (or, in some non-default rounding direction modes, the properly signed maximum-magnitude  finite  num-
       ber) in lieu of a value whose magnitude is too large, and raises the overflow and inexact exceptions.

       raises the underflow exception whenever a result is tiny (essentially subnormal or zero) and inexact.

       raises the inexact exception whenever a rounded result does not equal the mathematical result.

ERRORS
       If one of x and y is infinite, the other is zero, and z is not NaN, sets to

       If x times y is an exact infinity and z is also an infinity but with the opposite sign, sets to

       If the correct value would overflow, sets to

STANDARDS CONFORMANCE
