## Description

• This function gives the common logarithm of a complex number.
• In , where Complexnumber is in the form of . i.e & are the real numbers.
• And is the imaginary unit ..
• Log base 10, is known as the common Logarithm or Decadic logarithm, is the logarithm to the base 10.
• To find the common logarithm of a complex number, we have to calculate from the Natural Logarithm.
• So .
• We can use COMPLEX function to convert real and imaginary number into a complex number.
