# Infinity, -Infinity values in JavaScript

Such values as `Infinity` and `-Infinity` are obtained if some number is divided by zero. JavaScript does not throw an error, in such a case, as in other programming languages, but returns these values:

`alert( 1 / 0); // shows Infinity alert(-1 / 0); // shows -Infinity`

Divide the number `10` by `0`. Display the result on the screen.

Divide the number `-10` by `0`. Display the result on the screen.
