Notes on operand usage:
Please 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. This operation is
performed using floating-point numbers, and S must therefore be converted to a
floating point number.
 Content of operand D =e
When M0 is On, the value of (D1, D0) will be converted to a binary floating point

number, which will be stored in register (D11, D10).
 When M1 is On, the EXP operation is performed on the exponent of (D11, D10);
its value is a binary floating point number stored in register (D21, D20).
