How to use the EXP() function

  Hi Folks

  I am trying to achieve the following:

  BaseNumber = 2

  Exp1 = (BaseNumber)^1 (i.e. 2)

  Exp2 = (BaseNumber)^2 (i.e. 4)

  Exp3 = (BaseNumber)^3 (i.e. 8)

  How do I code it using the EXP() function in ProOrder???

  I don’t really understand what you try to do. EXP() gives you e^(the number in the brackets). So your base number (from your example) is not 2 but e=2.178….

  This formula is used like

  exp(2) : is 2×2 = 4

  exp(3) : is 3×3 = 9

  exp(a) can only do ^2, for your example you would idealy have a math formula syntax exp(b,e) which accepts b=base and e=exponent.

  But you could try whether exp( exp(2) ) works.

  I’m sorry but what you describe is just the square of a number. EXP() gives you the exponential function! It is e^(x) and this is approx 2.178^(x). Look at the pic attached. Here you see e^1=e=2.178…

  basenumber=2 a1=exp(1*log(basenumber)) a2=exp(2*log(basenumber)) a3=exp(3*log(basenumber)) return a1, a2, a3

  1 2 3 4 5 6 7

  basenumber=2   a1=exp(1*log(basenumber)) a2=exp(2*log(basenumber)) a3=exp(3*log(basenumber))   return a1, a2, a3

  (PS: added the return line just to display it in ProBuilder, but obviously if this is to include in a ProOrder piece of code you’d get rid of the return line)

  @Despair that’s the Euler number (DE: die Eulersche Zahl, sowas wie Pi für Logarithmus) and that’s why Noobywan has log(basenumber).
