Comparing LOG and LOG10
The LOG function returns the natural logarithm for the given float expression. Natural logarithms are calculated by using the base-2 system. However, the LOG10 function returns the base-10 logarithm. Use both LOG and LOG10 for trigonometric applications. For example, this SELECT statement calculates both the LOG and LOG10 of the value 1.75:
SELECT LOG(1.75), LOG10(1.75)
