EXP
Function
EXP(467) calculates the natural (base e) exponential of the 32-bit floating-point number in S+1 and S
and places the result in R+1 and R. In other words, EXP(467) calculates e
x
(x = source) and places the
result in R+1 and R.
The constant e is 2.718282.
The following diagram shows the relationship between the input data and result.
