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 need to have the same function for log to the base of 10.
I do not see log to the base of 10 under the math library, can someone let me know if that is an option available or how do I convert to Log10 instead of loge?

Thanks! Much Appreciated
I tried both methods but I am getting the following error -
I am getting the following Error:
for the other method -
I get the following error when I compile
Seems like both are giving error
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))
