Data Handling Instructions 5-9
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.
Degrees to Radians (RAD)
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.
Entering Parameters
• Source is the integer and/or floating point values.
• Destination is the address of the word where the data is to be stored.
Table 5.4 Processor Function
With this Bit The Processor
S:0/0 Carry (C) always resets.
S:0/1 Overflow (V) sets if overflow generated or an unsupported input is
detected; otherwise resets
S:0/2 Zero (Z) sets if the result is zero; otherwise resets
S:0/3 Sign (S) sets if the result is negative; otherwise resets
