Decimal points in monetary input group

[MarkWBC]

Some scenarios to consider:

• A user skips over the 'Rounded to the nearest $100'. They enter a dollar amount as well as cents e.g 200.50. What happens next?
• A user enters a different currency mark eg £. What happens next?

Potential solution:
Preferred

• Limit the field to numbers only
• Update Hint Text to include other input requirements/restrictions

Last resort

• Use error states to communicate input requirements

Not recommended

• Rounding numbers on behalf of the customer is taking control away from them, changing expectations, and potentially jarring.
