I want to round a (possibly negative) double towards zero (ending
up with another double). As far as I can tell, what I need to do is
x2 = copysign (floor (fabs (x1))), x1);
but it seems like there should be a simplier way. Is there? If it helps,
I can guarantee that the integral part of the double will fit into an int
with no loss of precision (i.e. -90 <= x <= 90).
