Float vs Double

Question

Is there ever a case where a comparison (equals()) between two floating point values would return false if you compare them as DOUBLE

Answer 1

You should be okay to make that cast as long as the equality test involves a delta.

For example: abs((double) floatVal1 - (double) floatVal2) < .000001 should work.

Edit in response to the question change

No you would not. The above still stands.
