1. Type in the expression you want to evaluate in the editor. The whole expression should be written in one line.

2. Press Ctrl+Enter to calculate the expression when the caret is in the line of expression.

There are two special variables in the ditor calculator:

$ans .If you want to use the value that was evaluated in the earler step, use a special variable named $ans.

$pi .The value of the variable $pi is 3.1415926535.

$ans / $pi = 3.338307

The editor supports basic mathematics functions which are very similar to those used in C math library.
