LOG10(n)


  • where 'n' is the positive real number.

Description

  • This function gives the logarithm value with the base 10.
  • The logarithm of x to base b is the solution y to the equation.i.e b^y=x.
  • For e.g The logarithm of 1000 to base 10 is 3.because 1000=10*10*10=10^3.
  • The logarithm of base 10 is called common logarithm or decimal logarithm.
  • It is denoted by log 10(x) or log(x).
  • 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).
  • For e.g:log(5260)=3.7209 ,that is nearly(next digit) to 4.
  • That is the number of digits of 5260(4).

Examples

  1. log 10(5)=0.698970004
  2. log(55)=1.740362689
  3. log(10)=1
  4. log(1)=0
  5. log(-10)=NaN
  6. log(0.25)=-0.602059991
