Hi,

What is the easiest way to calculate exponential function and natural logarithm in Dataverse? In a typical spreadsheet program you would typically use EXP() and LN() formulas. Is it as easy in Dataverse?

  Dataverse has pow() and log()  you can compute the exp() and ln() with two simple formulas.

  e=2.718281828459045   #add more digits as necessary for acuracy
  
  ln(x) = log(x) / log(e)

  exp(x) = pow(e,x)

   

  You can also use

  n=1000000000 #add more digits as necessary for acuracy
  e = pow((1+1/n),n)

  to compute the value of e
