Quick convertor between decimal and IEEE754 single or double precision float values. Entering a numeric value in the top box will show hex representations for single and double precision in the others. Entering a hex value in the single/double box will decode it to a numeric value. Hex values are right-padded, so you can just type the first few characters and hit enter if needs be. Also, you can just enter decimal values for the single/double entries and it'll immediately convert to hex and show the numeric decode.
