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).
