A set of helper functions for formatting, validating, and generating numeric values.

  • thousandsSeparator (optional): Character to use for thousands. Defaults to ",".

untitled
numberFormat(1234567.891, 2, ".", ","); // "1,234,567.89"
numberFormat(1234567.891, 3, ",", "."); // "1.234.567,891"

NumberOnly(value: any): number​
