Loss of precision - int -> float or double

Question

I have an exam question I am revising for and the question is for 4 marks.

\"In java we can assign a int to a double or a float\". Will this ever lose

Answer 1

There are two reasons that assigning an int to a double or a float might lose precision:

• There are certain numbers that just can't be represented as a double/float, so they end up approximated
• Large integer numbers may contain too much precision in the lease-significant digits
