A function returning 'e' to the power of the argument. The argument must be < 88.7228392. The 'natural' number, 'e', is approximately 2.71828183.
This function can be used as the 'anti-log' of a natural logarithm. Logarithms are 'traditionally' used for multiplication (by adding the logarithms) and division (by subtracting the logarithms). For example,
10 log1=LN(2.5) 20 log2=LN(2) 30 log3=log1+log2 40 answer=EXP(log3) 50 PRINT answer
will calculate 2.5*2 by adding their natural logarithms and print the answer.
