DEG - Convert Radians to Degrees
This instruction can only be used in the Expression parameter of the Calculate Expression (MATH) instruction.
The Convert Radians to Degrees (DEG) instruction converts real numbers in radian format to degree format. In radian format, a circle contains 2pi radians, In degree format, a circle contains 360 degrees. This instruction can convert between both positive and negative real numbers, and for angles greater than a full circle.
Note: Use the F9 key or click the 'three dot box' at the right edge of the parameter field to open the Default Element Selection Tool (the Element Picker or the Element Browser) or use the Down-Arrow key (Auto-Complete) on any parameter field to see a complete list of the memory locations that are valid for that parameter of the instruction.
Result specifies a location to store the result of the calculation. The result is always a real value even if the radian parameter is an integer, so this should be a writable Real (floating point) location.
The Expression parameter consists of all the text between the bounding parentheses. Any expression parameter can be a constant value, a bit or numeric memory location, an arithmetic expression, and / or mathematical function or other expressions up to a maximum of 1024 characters. Expressions can be nested, so use of parentheses is recommended to ensure proper evaluation order.
