DRAD, DRADP: 6 steps
Operands:
S
: Source device (degree)
D
: Conversion result (radian)
Explanations:
1. Use the following formula to convert degree to radian:
Radian
＝
degree
×
(
π
/180)
2. F refers to floating point input. Be sure to add a decimal point when using it.
3. Only 32-bit instructions DRAD and DRADP are applicable.
4. Flags:
OX O100
Zero flag M1808 M1968
Borrow flag M1809 M1969
Carry flag M1810 M1970
a) If the absolute value of the result exceeds the max. floating point value, carry flag will be ON.
b) If the absolute value of the result is less than min. floating point value, borrow flag will be ON.
c) If the conversion result is 0, zero flag will be ON.
Program Example:
When X0 = ON, convert degree value of the binary floating point in (D1, D0) to radian and save the binary floating
point result in (D11, D10).
