Gaussian Integers
Gaussian integers are complex numbers in which the real and imaginary
parts are integers.
The GaussInt package contains commands that perform Gaussian integer
operations.
The GIfactor command returns the Gaussian integer factorization.

You can enter the imaginary unit using the following two methods.
• In the Common Symbols palette, click the i or j item. See
Palettes (page 10).
• Enter i or j, and then press the symbol completion key. See Symbol
Names (page 16).
Note: In 1-D Math input, enter the imaginary unit as an uppercase i (I).
The GIsqrt command approximates the square root in the Gaussian integers.
