The I2F/I2FP instructions convert integer variables to float variables. Specify the integer variable or constant in S1 that you want to convert, and specify float variable for the conversion output in D1. You can specify only an integer variable for input in S1 and a float variable for output in D1. 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 an integer constant
When operand S1 is an integer constant and you want to input a hexadecimal value in operand S1
When 0x (zero and lower case "x") is input, the following values become hexadecimal values.
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.
