-An non-negative integer number is `pattern:\d+`. A zero `0` can't be the first digit,  but we should allow it in further digits.
-
-So that gives us `pattern:[1-9]\d*`.
-
-A decimal part is: `pattern:\.\d+`.
-
-Because the decimal part is optional, let's put it in parentheses with the quantifier `pattern:?`.
-
-Finally we have the regexp: `pattern:[1-9]\d*(\.\d+)?`:
-
-```js run
-let reg = /[1-9]\d*(\.\d+)?/g;
-
-let str = "1.5 0 -5 12. 123.4.";
-
-alert( str.match(reg) );   // 1.5, 0, 12, 123.4

-# Find positive numbers
-
-Create a regexp that looks for positive numbers, including those without a decimal point.

-An example of use:
-```js
-let reg = /your regexp/g;
-
-let str = "1.5 0 -5 12. 123.4.";
-
-alert( str.match(reg) ); // 1.5, 12, 123.4 (ignores 0 and -5)
