*The logarithm of base 10 is called Common Logarithm or Decimal Logarithm.
*It is denoted by <math>\log_{10}</math> or <math>log(x)</math>.
*It is denoted by <math>\log_{10}</math> or <math>log(x)</math>.
*log10(x) is related to the number of decimal digits of a positive integer x: the number of digits is the smallest integer strictly bigger than log10(x).
*<math>\log_{10}(x)</math> is related to the number of decimal digits of a positive integer x: the number of digits is the smallest integer strictly bigger than <math>\log_{10}(x)</math>.
*For e.g:log(5260)=3.7209 ,that is nearly(next digit) to 4.
