Degrees (DEG)
When enabled, the DEG instruction converts the Source (in radians) to degrees and stores the result in the Destination.
The DEG instruction uses this algorithm:
Source*180/pi = Source*57.29578

Operands
IMPORTANT:
Unexpected operation may occur if:
- Output tag operands are overwritten
- Members of a structure operand are overwritten
- Except when specified, structure operands are shared by multiple instructions.
There are data conversion rules for mixing numeric data types within an instruction. See Data conversions.

Condition/State | Action taken |
|---|---|
Prescan | N/A |
Rung-condition-in is false | Set Rung-condition-out to Rung-condition-in. |
Rung-condition-in is true | Set Rung-condition-out to Rung-condition-in. Dest = degree value of the Source. |
Postscan | N/A |
