LOG10(Number)


  • where 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).

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
