IMSUB function

PRO BASIC

In Jspreadsheet Formulas Pro, the IMSUB function is used to calculate the difference between two complex numbers. This function takes two arguments, each representing a complex number. It subtracts the second complex number from the first one. The result of this function is a complex number which is the difference between the two input complex numbers.

Documentation

Returns the difference between two complex numbers.

Syntax

IMSUB(inumber1, inumber2)

Parameter	Description
`inumber1`	The complex number from which you want to subtract another complex number.
`inumber2`	The complex number that you want to subtract from the first complex number.

Behavior

The IMSUB function subtracts two complex numbers. It takes two arguments: the first complex number and the second complex number to be subtracted from the first one.

When given empty cells for any of the arguments, IMSUB treats them as zeroes.
If text values are provided as arguments, IMSUB will attempt to parse them as complex numbers. If the parsing fails, it will return a #VALUE! error.
The function doesn't support boolean values. If a boolean value is provided as the argument, the function will treat it as an integer (TRUE as 1 and FALSE as 0).
IMSUB expects the complex numbers to be provided in the form of a+bi or a+bj, where a and b are the real and imaginary parts respectively. If the complex numbers are not in the correct format, the function will return a #NUM! error.
In case of any other errors, like providing more or less number of arguments than required, IMSUB will return a #VALUE! error.

Common Errors

Error	Description
`#VALUE!`	This error is returned when the given arguments are not recognized as valid complex numbers. This can happen if the arguments are boolean values, or if they are text values that cannot be parsed as complex numbers.
`#NUM!`	This error is returned when the given complex numbers are not in the correct format. The correct format is `a+bi` or `a+bj`, where `a` and `b` are the real and imaginary parts respectively.

Best practices

Always ensure that the complex numbers provided as arguments are in the correct format. The correct format is a+bi or a+bi j, where a and b are the real and imaginary parts respectively.

To avoid unexpected errors, do not provide boolean values as arguments to this function.

Use error handling functions like IFERROR in combination with IMSUB to handle possible errors gracefully.

Be aware that IMSUB treats empty cells as zeroes. If this is not the desired behavior, make sure to provide valid complex numbers for both arguments.

Usage

A few examples using the IMSUB function.

IMSUB("1+i", "2+3i") returns "-1-2i"
IMSUB("3+4i", "-1+2i") returns "4+2i"
IMSUB("0+0i", "5-2i") returns "-5+2i"
IMSUB(4, 2) returns "2"   // Treated as real numbers
