| $number1 | mixed | Scalar (string/int/float/bool) |
| $action | string | Calculation action to execute. Valid input: '+' or 'add' or 'addition', '-' or 'sub' or 'subtract', '*' or 'mul' or 'multiply', '/' or 'div' or 'divide', '%' or 'mod' or 'modulus' '=' or 'comp' or 'compare' |
| $number2 | mixed | Scalar (string/int/float/bool) |
| $round | boolean | Whether or not to round the result. Defaults to false. Will be disregarded for a compare operation |
| $decimals | integer | Decimals for rounding operation. Defaults to 0. |
| $precision | integer | Calculation precision. Defaults to 10. |
| return | mixed | Calculation result or false if either or the numbers isn't scalar or an invalid operation was passed - for compare the result will always be an integer - for all other operations, the result will either be an integer (preferred) or a float |
