Exp() function

[Bruno]

Hi there,

A simple question :-)

How to compute the exp() function in Basic4ppc ?
exp(1) = 2.718281828459045
exp(-1) = 0.36787944117144233

Many thanks,

Bruno.

Thanks Agraham, but ...

I have a formula with something like


result=exp(tmp)

tmp can be positive or negative.

How calculate result?

Is this ok
for:
result = exp(tmp)

in Basic4PPC
result = cE^(tmp)

Sub exp(num)
  If num < 0 Then
    Return 1/(cE^Abs(num))
  Else
    Return cE^num
  End If
End Sub

Thanks a lot Agraham.
