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
- log 10(5)=0.698970004
- log(55)=1.740362689
- log(10)=1
- log(1)=0
- log(-10)=NaN
- log(0.25)=-0.602059991
