IMARGUMENT

Returns the argument of a complex number.

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

Syntax:

IMARGUMENT(complexnumber)

complexnumber is text representing a complex number, for example as a+bi or a+bj.
IMARGUMENT returns the argument of complexnumber in radians - that is, in a polar representation, the angle relative to the horizontal axis. For a complex number a+bi = r(cosφ + isinφ) the argument is φ.

Example:

IMARGUMENT("3+3i")

returns 0.785398163397 - that is 2π/8 radians.
