IMABS

The Excel IMABS function returns the absolute value of a complex number. For example: The absolute value of a complex number goes by several other names: modulus, length, or magnitude. All of them refer to the same thing. When we draw the arrow representing a complex number, the absolute value is equal to the distance from the origin to the tip of the complex number. The IMABS function always returns a positive number. For example, consider the complex number "-12-5i" which points in a different direction. The absolute value of this complex number is positive 13. In general, the absolute value of a complex number "z=x+yi" is given by the formula below.
