IMABS

Returns the absolute value of a complex number.

This function is only available if the Analysis AddIn is installed.

Syntax:

IMABS(complexnumber)

complexnumber is text representing a complex number, for example as a+bi or a+bj.

IMABS returns the absolute value or modulus of complexnumber - that is, in a polar representation, the distance from the origin. If complexnumber is a+bi, then the absolute value is √(a² + b²).

Example:

IMABS("4+3i")

returns 5.

Issues:

• This function currently appears in the AddIn category of the Function Wizard.
