Question

I am trying to convert a Minimum Bounding Rectangle from double values to float values. After the conversion, I need the (float) rectangle to be equal to or contain the (double) rectangle (the float rectangle needs to be bigger than or equal to the double rectangle). To do that I want to be able to specify which way to round the double to convert it to float. So, when casting the “Top” of the rectangle, I would round up, but when casting the “Bottom” of the rectangle, I would round down.

Is there a class that allows me to do this?

Thanks.

You can compare the float to the double and if it needs to be slightly larger or smaller you can call floatToIntBits and intToFloatBits with an increment or decrement as required.
