IMARGUMENT


Description Computes the argument as an angle expressed in radians.

Syntax IMARGUMENT ( complex_number)
Argument Description
complex_number A complex number in the form (a + bi). You may enter either or both components of the complex number. See COMPLEX for details.If the complex number or imaginary component of a complex number is entered within the function's argument list, it must be enclosed within quotation marks (e.g., IMABS("1+1i") or IMABS("i")).

Equation

Remarks This is the complementary function to IMABS, where the degree of angle () begins at the positive X-axis, and rotates counterclockwise in polar coordinates.

An alternate form of complex notation is r(cos + i sin ) where "r" is the result of IMABS.

Note The range of is - < <= .

Example This function returns 0.785398163:

IMARGUMENT("1+1i")

This function returns 3.14159265, the value :

IMARGUMENT(-1)
