RAD - Convert Degrees to Radians

This instruction can only be used in the Expression parameter of the Calculate Expression (MATH) instruction.

The Convert Degrees to Radians (RAD) instruction converts real numbers in degree format to radian format. In degree format, a circle contains 360 degrees. In radian format, a circle contains 2pi radians. This instruction can convert between both positive and negative real numbers, and for angles greater than a full circle.

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.
