How to get LOG to the base 10 in FICO
I have the following formula to get a score in FICO - SCORE = math().max(0, math().min(-100-math().log(aFinalVar)*400, 1000)) The bold part has the LOG function which is log to the base of e, I ne...
To compute a log base 10, you can use the logarithm change of base rule that says:
log (base b) a = (log (base d) a) / (log (base d) b)
so in your example you would use
math().max(0, math().min(-100-(math().log(aFinalVar)/math().log(10))*400, 1000))
