This PR closes [Issue #13482](https://github.com/nushell/nushell/issues/13482) # Description This PR tend to make all math function to be constant. # User-Facing Changes The math commands now can be used as constant methods. ### Some Example ``` > const MODE = [3 3 9 12 12 15] | math mode > $MODE ╭───┬────╮ │ 0 │ 3 │ │ 1 │ 12 │ ╰───┴────╯ > const LOG = [16 8 4] | math log 2 > $LOG ╭───┬──────╮ │ 0 │ 4.00 │ │ 1 │ 3.00 │ │ 2 │ 2.00 │ ╰───┴──────╯ > const VAR = [1 3 5] | math variance > $VAR 2.6666666666666665 ``` # Tests + Formatting Tests are added for all of the math command to test there constant behavior. I mostly focused on the actual user experience, not the correctness of the methods and algorithms. # After Submitting I think this change don't require any additional documentation. Feel free to correct me in this topic please.
