ES2015-compliant shim for Number.isNaN - the global isNaN returns false positives.
A very simple currency mask directive for Angular that allows using anumber attribute with the ngModel. In other words, the model is anumber, and nota string with a mask. It was tested in Angular version 13.
jQuery.numeric() allows only valid numbers to be typed into a text box. Can take negative numbers and a decimal point. You can also supply a callback that runs when focus is lost and the value in the text box is nota valid number.
Checks if anumber is not positive. Resting on the shoulders of giants.
