S: Exponent D: Operation result
The base is e = 2.71828 and exponent is S
[
[ D +1，D ]=EXP
S +1，S
Both positive and negative values are valid for S. Register D has to be
32-bit format. Operation is conducted in floating point value, so the value in
S needs to be converted into floating value before exponent operation.
S
The content in D =e
When M0 = ON, convert (D1, D0) to binary floating value and save the
result in (D11, D10).
Wehen M1= ON, perform exponent operation with (D11, D10) as the
exponent. The value is saved in register (D21, D20) in binary floating format.
