When using this directive, losing decimal points and view value is getting distorted after 12 characters before the decimal (the num-int is set to 200). See screenshot

Than you for your feedback. Very interesting case. I will check it if I can fix it somehow. In this module everything rely on normal js numbers.

Spent some time digging into the problem and the issue lies in the fact that Javascript limits the size of integers to 64-bit floating point values. When you convert the input to Number, it causes the JS engine to automatically convert to scientific notation, thus throwing things off. I removed the conversion to Number, as well as any computation on that number so to get the full number represented in string form and work off that.
