IMLOG2 function

PRO BASIC

The IMLOG2 function in Jspreadsheet Formulas Pro is a useful tool when dealing with complex numbers. It's primarily used to calculate the base-2 logarithm of a given complex number. In simpler terms, it's like asking "2 to what power will give me this complex number?" This function can be especially handy for various mathematical and scientific calculations.

Documentation

Returns the base-2 logarithm of a complex number.

Syntax

IMLOG2(inumber)

Parameter	Description
`inumber`	The complex number for which you want to calculate the base-2 logarithm.

Behavior

The IMLOG2 function is used to calculate the base-2 logarithm of a complex number. The complex number can be in the form of x+yi or x+yj.

If the cell reference or complex number argument is empty, the function returns a #NUM! error.
If the complex number argument is non-numeric, the function also returns a #NUM! error.
If the complex number argument includes a boolean value, the boolean is treated as a numeric value where TRUE is equivalent to 1 and FALSE is equivalent to 0.
If the complex number argument includes an error, the function propagates that error.

Common Errors

Error	Description
#NUM!	This error occurs when the cell reference or complex number argument is empty or non-numeric.
#VALUE!	This error occurs when the complex number argument is in incorrect format. The correct format is either `x+yi` or `x+yj`

Best practices

Always ensure the complex number is in the correct format (x+yi or x+yj).

Avoid using boolean values in the complex number argument unless your use case specifically requires it.

Always handle errors appropriately to prevent propagation of errors.

Use the 'IMLOG2' function with other complex number functions for more advanced calculations.

Usage

A few examples using the IMLOG2 function.

IMLOG2("1+i")   // Returns 0.5+1.1330900354568i
IMLOG2("2+2i")  // Returns 1.5+1.1330900354568i
IMLOG2("5-3i")  // Returns 2.54373142062517-0.779660533040064i
