IMLOG10(z)

• $z$ is the complex number is of the form $x+iy$

Description

• This function gives the common logarithm of a complex number.
• IMLOG10(z), where $z$ is the complex number in the form of $x+iy$. i.e $x$ & $y$ are the real numbers.
• $I$ is the imaginary unit .$i={\sqrt {-1}}$.
• 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 $log10(x+iy)=(log_{10}e)ln(x+iy)$.
• We can use COMPLEX function to convert real and imaginary number into a complex number.

Examples

1. =IMLOG10("6+7i") = 0.964709462857146+0.37443569720420i
2. =IMLOG10("4-5i") = 0.806391928359868-0.389151908999031i
3. =IMLOG10("8") = 0.903089986991944
4. =IMLOG10("3i") = 0.477121254719662+0.682188176920921i
5. =IMLOG10("0") = NULL

• Imln("8") for that it should consider the imaginary value is zero.
