How to use the EXP() function

juanj · 2017-10-12T15:48:01+00:00

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???

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
```

(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).

That’s what I was saying… 🙂
