Annoying numbers validation

Annoying numbers validation

Hello,

   I'm trying out the bassassist validation plugin to validate some form fields.  One particular one - the user
types in an amount of money.  I used "number" for it.  Say the user types in 100.00:  user types the "1" - all
happy.  Then the first and second zeros - all still OK.  Then he types the decimal point - and an error breaks loose, because "100." is not a good number.  Then he hits the two zeros afterwards and all is again OK.

   What's a good way to let the user type in the whole number without annoying her with a bogus error message while she's typing?
