Chapter 6 Applied Instructions Example When M0 is ON, the FATAN instruction finds the arctangent of the floating-point number in (D1, D0) and stores it in (D11, D10). The FDEG instruction converts the arctangent value in (D11, D10) is converted into degrees, and stores the conversion result in (D21, D20).
