Or you can enter a binary number, a hexnumber or the decimal representation into the corresponding textfield and press return to update You can either convert a number by choosing its binary representation in the button-bar, the other fields will be updated immediately. IEEE-754-Standard contains formats with increased precision. The conversion is limited to 32-bit single precision numbers, while the There can be surprising differences in what numbers can be represented easily in decimal and which numbers can be represented in IEEE-754. This is the format in which almost all CPUs represent non-integer numbers. This webpage is a tool to understand IEEE-754 floating point numbers. So you can easier tell the difference between what you entered and what you get in IEEE-754.
The difference between both values is shown as well, Entering '0.1' is - as always - a nice example to see this behaviour. Well as the actual full precision decimal number that the float value is representing. Now the original number is shown (either as the number that was entered, or as a possibly rounded decimal string) as Previous version would give you the represented value as a possibly rounded decimal number and the same number with the increased precision
There has been an update in the way the number is displayed.
