IMLN function

PRO BASIC

The IMLN function in Jspreadsheet Formulas Pro is a mathematical tool that allows you to find the natural logarithm of a complex number. A complex number is a number that includes both a real part and an imaginary part. By using IMLN, you input your complex number and the formula will output its natural logarithm. This function is especially useful in advanced math or physics calculations that involve complex numbers.

Documentation

Returns the natural logarithm of a complex number.

Syntax

IMLN(inumber)

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

Behavior

The IMLN function is used to return the natural logarithm of a complex number. Here is how it handles various inputs:

Empty cells: If the IMLN function is used on an empty cell, it will return an error because it needs a complex number to perform the calculation.
Text: The IMLN function does not work with text. If a cell containing text is used as an argument, the function will return an error.
Booleans: The IMLN function does not work with Boolean values. If a cell containing a Boolean value is used as an argument, the function will return an error.
Errors: If the cell used as an argument contains an error, the IMLN function will also return an error.
Complex Numbers: The IMLN function is designed to work with complex numbers. It will return the natural logarithm of the complex number provided as an argument.

Common Errors

Error	Description
#VALUE!	This error occurs when the input to the `IMLN` function is not a valid complex number.
#NUM!	This error occurs when the input is a purely real negative number (imaginary part = 0), which is outside the valid domain for real logarithms.
#DIV/0!	This error occurs when the complex number provided as an argument is 0.

Best practices

Always ensure that the input to the IMLN function is a valid complex number.

Avoid using cells that contain text, Boolean values, or errors as arguments to the IMLN function as this will result in an error.

Handle zero input carefully to avoid the #DIV/0! error.

Usage

A few examples using the IMLN function.

IMLN("1+i")     // Returns 0.346573590279973+0.785398163397448i
IMLN("2+2i")    // Returns 1.03972077083992+0.785398163397448i
IMLN("5-3i")    // Returns 1.76318026230808-0.540419500270584i
