Gaussian primes

The Gaussian integers are complex numbers of the form a+bi where a and b are (standard) integer numbers. These numbers can be factored in Gaussian primes.

The applet above shows the Gaussian primes where |a| < 10000000 and |b| < 10000000. The prime numbers are marked in green.

Move the graph by clicking in the arrows or using the arrow keys. You can obtain more detail or see a larger area using the magnifying glass buttons.

You can also see the position a + bi in the complex plane of any point of the graph by moving the cursor to that point.

Move the center by typing a new complex number in both input boxes (up to 7 digits each) and press the return key.
