In SugarCRM we oft record a persons birth date (in the field birthdate). Sometimes it’s useful to know how old this person is. So we create a new field age_c (note: this can be of field type Integer or Decimal) and then using this formula we can see how old they are:
If you use a Decimal field type you can remove the floor() portion of the formula so that it doesn’t round it down. This means you will see just how old they are to a decimal point. Personally I tend to prefer just knowing that they are 21 or 42 rather than 21.45 or 42.01.
