  iMath is not initialized before you use it in the calculation of the value of iMath. Read the code. Where does the value of iMath come from when you use it in and iMath * edmathm.value?

You are trying to set iMath to a value using iMath. The right hand side of your assignment is undefined.

  But doesn't Delphi always assign a default value like '0'? so it should be defined, or am I misunderstanding something?

  Depends on the type, but most of them are not. Interfaces are a notable exception, and strings also have a valid value, although that doesn't always mean they are empty..
