       atan2d64(),  atan2d128(),  atan2d32() - decimal arctangent and quadrant
       functions

SYNOPSIS
DESCRIPTION
       The function returns the arctangent of y/x, using  the  signs  of  both
       arguments to determine the quadrant of the return value.

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

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

RETURN VALUE
       If y and x is −0,

       If y and x is +0,

       If y and x is less than 0, returns

       If y and x is greater than 0, returns

       If y is less than 0 and x is 0, returns

       If y is greater than 0 and x is 0, returns

       If y is greater than 0 and x is −infinity, returns

       If y is less than 0 and x is −infinity,

       If y is greater than 0 and x is infinity, returns +0.

       If y is less than 0 and x is infinity, returns −0.

       If y and x is finite, returns

       If y and x is −infinity, returns
