Note that the usage is case insensitive so `InFiNiTy` is a valid value. - -Some calculations (such as `sin(-infinity)`) might return `NaN` as per the spec. Given that `NaN` can't be replaced with a value that's useful to CSS it is left as is, as the result will be effectively ignored by the browser. - -## Options - -### preserve - -The `preserve` option determines whether the original notation -is preserved.
