The F2R/F2RP instructions convert float variables to real variables. Specify the float variable or constant in S1 that you want to convert, and specify real variable for the conversion output in D1. You can specify only a float variable for input in S1 and a real variable for output in S2. Use the convert instruction when you want to use different variable types in a calculation or comparison.
Refer to the following for specifying a constant.
When operand S1 is a float constant
Note that specified arrays (entire arrays) cannot be converted.
When operands S1 and D1 specify the entire array, an error will occur even if the specified variables are the same type.
