sure to use 32-bit data format to assign the D register. Because
using the floating point format to perform the EXP operation is necessary,
S has to be converted to the floating point value.
The content value of D operand= e S ; e=2.71828, S is the assigned
source data.
(Zero flag, Carry flag, Overflow flag are valid and Error flag M1067,
M1068 read D1067, D1068)

Ϩʳ When M0 is ON, the data of (D0, D1) is converted to decimal of binary
number system and the result is stored in the (D10, D11) register.
Ϩʳ When M1 is ON, use (D10, D11) as exponent to perform the EXP
operation. The result is decimal of binary number system and will be
stored in the (D20, D21) register.
Ϩʳ When M2 is ON, the data of (D20, D21) is converted from binary to
decimal and the result is stored in (D30, D31) register. (At that time, the
D31
result=D30 x 10 )
