NAME
       fma(), fmaf(), fmaw(), fmal(), fmaq() - floating multiply-add functions

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

       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.

       The  and	 macros	 are  defined in indicating that are each as fast as a
       multiply and add.

USAGE
       These functions are available only for Integrity servers.

       To use these functions, compile either with the default option or  with
       the and options.

       To use or compile also with the option.

       To  use	these  functions,  make sure your program includes Link in the
       math library by specifying on the compiler or linker command line.

RETURN VALUE
       If one of x and y is infinite, the other is  zero,  and	z  is  a  NaN,
       returns NaN and optionally raises the invalid exception.

       If  one	of x and y is infinite, the other is zero, and z is not a 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	a  properly signed infinity in lieu of a value whose magnitude
       is too large, and raise 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.

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

ERRORS
       No errors are defined.
