This is documentation for Refine 4.xx.xx , which is no longer actively maintained.
This field is used to display a number formatted according to the browser locale, right aligned. and uses Intl  to display date format.
Good to know : 
You can swizzle this component with the Refine CLI   to customize it.
Usage  <NumberField> uses Intl.NumberFormat() if available, passing the locales and options props as arguments. This allows a perfect display of decimals, currencies, percentages, etc.
See Intl.NumberFormat documentation  for the options prop syntax.
If Intl is not available, <NumberField> outputs numbers as is (and ignores the locales and options props).
Live previews only work with the latest documentation.
