To return e (the base of natural logarithms) to the power of x.
x must be less than 88.02969.
If EXP overflows, the "Overflow" error message appears; machine infinity with the appropriate sign is supplied as the result, and execution continues.
EXP(x) is calculated in single precision, unless the /d switch is used when GW-BASIC is executed.
10 X = 5 20 PRINT EXP(X-1) RUN 54.59815
Prints the value of e to the 4th power.
