The function LOG10 calculates the logarithm to the base 10 of the given number. For the non-mathematicians out there: x=10LOG10(x).
Examples
100 INPUT "Integer Number:"!x
110 PRINT "This number has"!INT(1+LOG10(ABS(x)))!"digits."
The trivial function LOGN finds the logarithm of x to any base b which makes sense:
10 DEFine FuNction LOGN (x,b)
20 RETurn LN(x)/LN(b)
30 END DEFine LOGN
