Number Input

v1.0.0·Added in 1.0.0

A field for numbers people type or step: steppers with hold to repeat, min, max and step, and Intl formatting for money and units.

Type a number the way you write it: 1.234,5 in Romanian or 1,234.5 in English both work, a comma or a dot is taken as the decimal, and letters are simply refused (a refused key typed over a selection keeps it selected). At rest the field shows the formatted value ($125,000, 2.5 kg); focus it and it turns into the plain number, ready to edit, and Tab selects it all like any field. Press + or - to step, and hold either one: after a short pause it repeats, faster the longer you hold, and stops at min or max, where that button dims. ArrowUp and ArrowDown step, Shift or PageUp and PageDown take the large step, Home and End jump to min and max, Enter commits and still submits the form, Escape puts back the last committed value. With the field focused the mouse wheel steps too, without scrolling the page. A number typed past a bound shows the red ring until you leave the field, where it snaps back inside (or cannot be typed at all with strict clamping). On a phone the keypad is numeric (decimal when the step allows decimals), the text is 16px so iOS never zooms, the md box grows to 44px, each + and - has a 44px hit area (the stacked chevrons turn into a row of two 44px buttons), and a finger that starts scrolling on a stepper undoes its step. iOS keypads have no minus key, so negative values come from the steppers.
