LOG10(Number)

• where $Number$ 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 $b^{y}=x$.
• 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 or Decadic Logarithm.
• It is denoted by $\log _{10}$ or $log(x)$.
• $\log _{10}(x)$ is related to the number of decimal digits of a positive integer x: the number of digits is the smallest integer strictly bigger than $\log _{10}(x)$.
• For e.g:log(5260)= 3.7209, that is nearly(next digit) to 4.
• That is the number of digits of 5260(4).

ZOS

• The syntax is to calculate LOG10 in ZOS is $LOG10(Number)$.
  • where $Number$ is the any positive real number.
• For e.g.,[25..35]@LOG10.
• [25..50..3]@LOG10
