2) '''Numbers''': Numbers always need to be entered accurately. Consider how you would store currency data. When you use the Numeric validation and Currency [[Number Format|formatting]] on a custom field, the system actually stores the number value to the full number of decimals and without a [[:Category:Currency|currency]] symbol (i.e. "12.948576"). However, when the system displays this field, it is rounded to two decimals and with a currency symbol (i.e. "$12.95").
3) '''In General''': It's important to have a specific format for any standard data. Take for example, the Canadian postal code which one could enter as "M5V 2H1" or "M5V2H1" (among other variants using lower/upper case letters). The best practice for this example would be to enforce that the user always enters one specific format with upper case letters. This can be done using the [[JavaScript Validation|validation configuration ]] of a custom field.
