Notes on operand usage:
Refer to the function specifications table for each device in series
for the scope of device usage.
 S: operation source device. D: operation results device.
Taking e =2.71828 as a base, S is the exponent in the EXP operation.

 [ D +1, D ]=EXP
 Valid regardless of whether the content of S has a positive or negative value. The
designated register D must have a 32-bit data format. Performs the operation
using floating point numbers, and converts S to a floating point number.
 Content of operand D = e
 When M0 is ON, converts the value of (D1, D0) to a binary floating point
number, and stores the result in register (D11, D10).
 When M1 is ON, performs the EXP operation on the exponent of (D11, D10),
converts the result to a binary floating point number and stores it in register
(D21, D20).
