// the user's locale is English and they type in "1,234" we _do_ need to
|
|
// normalize the number to "1234" because HTML 5's valid floating-point
|
|
// number format does not allow the ',' grouping separator. We can detect all
|
|
// the cases where we need to convert by seeing if the locale-specific
|
|
// parsing function understands the user input to mean the same thing as the
|
|
// HTML-5-conforming parsing function. If so, then we should return the value
|

// as-is to avoid normalization. Otherwise, we return the de-localized
