Returns the argument q (theta), an angle expressed in radians, such that:
If this function is not available, run the Setup program to install the Analysis ToolPak. After you install the Analysis ToolPak, you must enable it by using the Add-Ins command on the Tools menu.
Inumber is a complex number for which you want the argument q.
- Use COMPLEX to convert real and imaginary coefficients into a complex number.
- If inumber is not in the form x + yi or x + yj, IMARGUMENT returns the #NUM! error value.
- IMARGUMENT is calculated as follows:
z = x + yi
IMARGUMENT("3+4i") equals 0.927295
