    onChange={this.onPriceChange}   // function (value: number | null, event: Event)
    value={this.state.price}        // normal react input binding
    placeholder="Enter price"       // all other input properties are supported
    min={0}                         // optional, set minimum allowed value
    max={100}                       // optional, set maximum allowed value
    format="0,0[.]00"               // optional, numbro.js format string. Defaults to "0,0[.][00]"
/>

All properties supplied to NumberInput will also be transferred to the resulting input element (e.g., style or className).

Supported event handlers

All event handlers supported by <input /> are supported. Except onChange received the current number as its first argument and the Event object as second argument.
