IMABS function

PRO BASIC

In Jspreadsheet Formulas Pro, the IMABS function is utilized to calculate the absolute value or magnitude of a complex number. A complex number is a number that can be expressed in the form a + bi, where 'a' and 'b' are real numbers, and 'i' is an imaginary unit. When you input a complex number into the IMABS function, it will provide you with the number's absolute value, essentially its distance from the origin on a complex number plane. This function is particularly useful in mathematical and engineering calculations.

Documentation

The IMABS function is used to return the absolute value (magnitude) of a complex number.

Syntax

IMABS(inumber)

Parameter	Description
`inumber`	The complex number for which to find the absolute value.

Behavior

The IMABS function takes a complex number in the format x + yi or x + yj and returns the absolute (modulus) value of the complex number. Here's how it handles different inputs:

If the input cell is empty, the function will return a #NUM! error, as it expects a complex number as an argument.
If the input is not a valid complex number, the function will return a #NUM! error.
Text inputs that can't be interpreted as complex numbers will result in a #NUM! error.
Booleans are not valid inputs for the IMABS function and will result in a #NUM! error.
If the referenced cell contains an error (such as #REF!, #DIV/0!, or other calculation errors), IMABS will return the same error without calculation.

Common Errors

Error	Description
`#NUM!`	Occurs when the input cell is empty, the input is not a complex number, or if a boolean is used as input.
`#VALUE!`	If the function encounters this error in the input cell, it will propagate the same error. Other error types from input cells will also be propagated.

Best Practices

Ensure that the input to the IMABS function is a valid complex number in the format x + yi or x + yj.

Avoid using the function with empty cells, booleans, and non-complex numbers to prevent a #NUM! error.

Be careful while referencing cells as the function will propagate any error from the input cell.

Use error handling functions like IFERROR or ISERROR to handle possible errors before using IMABS.

Usage

A few examples using the IMABS function.

IMABS("2+3i")         // Returns approximately 3.6056 (√(2² + 3²))
IMABS("-4-3i")        // Returns exactly 5 (√(16 + 9))
IMABS("0+10i")        // Returns exactly 10 (purely imaginary number)
IMABS("5+0i")         // Returns exactly 5 (purely real number)
IMABS(A1)             // Returns the modulus of the complex number stored in cell A1
