5.6.8 Exponential (EXP)
( 1 ) Operation
The EXP instruction calculates the value obtained by raising base e of the natural logarithm to the real number input
data and stores the result in the output data.
Œ “e” is the base of the natural logarithm.
( 2 ) Format
∗ C and # registers cannot be used.
( 3 ) Programming Example
The following programming example calculates base e of the natural logarithm raised to 1.0 in the input data in
MF00000, and stores the result in the output data in DF00000.
e
1.0 → DF00000 = 2.718282
If the operation result overflows, the output data will be set to the maximum value 3.402E+38 and an operation error will not
occur.
