Well, there is log10(). Or there is counting digits upward until your number is smaller than 10^digits. There are other counting methods too.
One question you are going to have to deal with is what to do if the number is negative. Another question to deal with is what to do if the number is between -1 and +1, such as 0.00043

I'd go with what Walter mentioned. However, in general length is the ideal way to go.
