Number of input and output field

Number of input field	:	One
Number of output field	:	One

This transformation function is used to calculate the logarithm value of an input value. In mathematics, the logarithm (Log) is the inverse function of exponentiation.
The parameter acts as the base of the logarithm (by default e ≈ 2.718).

If    ^aLog(b) = c, that means b = a^c, where a is the base of logarithm.

Examples :

  ²Log(4) = 2
  ²Log(0.5) = -1
  ¹⁰Log(100) = 2
  ¹⁰Log(0.1) = -1
