FixATan2
FixATan2 Extract arctangent of the quotient of two 32-bit values long opA ; dividend
long opA ; divisor
returns arctangent of quotient of opA / opB
FixATan2 returns the arctangent quotient of opA / opB in radians. opA and...
opB are two 32-bit values. Both should be the same data type; either
Returns: a 32-bit Fixed value; the arctangent of opA / opB, expressed in radians.
