compare IEEE double precision value to 0.0

Compare y to 0.0, set the condition codes for less than, greater than, or equal to 0.0. Set the return value c to -1 if less than, to +1 if greater than, or 0 if equal to 0.0.

y

IEEE double precision floating point value

c = 1 cc = gt for (y > 0.0)

c = 0 cc = eq for (y == 0.0)

c = -1 cc = lt for (y < 0.0)
