Dirichlet character calculator

Evaluate a Dirichlet character at an integer.

How to use this calculator

Edit DirichletCharacter(modulus,index,integer). Index 1 selects the principal character.

Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

Interactive tools require JavaScript. You can read the guide and example without it.

What to know

Character indexing follows CE's Wolfram-compatible convention; non-coprime integers have value zero.

Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
