LOG10(Number)
- where is the any positive real number.
is the any 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 .
- For e.g The logarithm of 1000 to base 10 is 3. Because 1000 = 10*10*10 = .
- The logarithm of base 10 is called Common Logarithm or Decimal Logarithm or Decadic Logarithm.
- It is denoted by or .
- is related to the number of decimal digits of a positive integer x: the number of digits is the smallest integer strictly bigger than .
- For e.g:log(5260)= 3.7209, that is nearly(next digit) to 4.
- That is the number of digits of 5260(4).

is related to the number of decimal digits of a positive integer x: the number of digits is the smallest integer strictly bigger than ZOS Section
- The syntax is to calculate LOG10 in ZOS is .
- where is the any positive real number.
- For e.g.,[25..35]@LOG10.
- [25..50..3]@LOG10
.
Examples
- =log 10(5)= 0.698970004
- =log(55)= 1.740362689
- =log(10)= 1
- =log(1)= 0
- =log(-10)= NaN
- =log(0.25)= -0.602059991
