what constitutes a integer or double in Java source is different that
in data. Data is laxer since you KNOW the type to be coerced to.
However if you wanted to enforce stricter rules, write a regex to
describe your allowed patterns (e.g. precise number of decimal
places), or see what effects you can get with a DecimalFormat and a
mask using the parse method.
