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.
