IMLOG10(Complexnumber,Base)
- is of the form
- is value of the base.
is of the form 
is value of the base.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.
, where Complexnumber is in the form of 
& 
are the real numbers.
is the imaginary unit .
.
