• Remove type="number" to avoid all sorts of weird behaviours in native number input. More details from Why the GOV.UK Design System team changed the input type for numbers
• Always clamp modelValue between "min" and "max"
• Disable the increment and decrement buttons when clicking the next step would exceed the 'max' and 'min' values, respectively
• Up and down keys trigger increment and decrement respectively
• Right and left keys trigger go forward and backward navigation
• Only numbers, +, - and dot are allowed to type in
• Fully support decimal step, using toFixed() to cope with JS Floating-Point Precision Issues
