Output Instruction
Updates to Arithmetic Status Bits
The arithmetic status bits are found in Word 0, bits 0 to 3 in the status file.
After an instruction is executed, the arithmetic status bits in the status file are
updated.

Use this instruction to convert degrees (source) to radians and store the result
in the destination. The following formula applies.
Source * Π/ 180
where Π = 3.141592
Use this instruction with SLC 5/03 (OS302), SLC 5/04 (OS401), and
SLC 5/05 processors.
Example: Convert 135 degrees to radians.
