How to place a mathematical function in a field

I have the following fields for my product:

NAME(char); MASS(int); PRICE(float); VALUE(float)

What I would like to do is to automatically calculate the total value of the product by multiplying the MASS with the PRICE ((MASS*PRICE)/100) in the VLAUE field. How and where do I place this function?

Thanks

@Dzingai what you need is to change the value field into a function field.  In new API (v8) you need to put the compute attribute in the field definition.  In both you need to develop a method in the said model to be used by the function.

You can find sample in the account.invoice modules which have quite a lot of function fields.
