This site works best with JavaScript enabled! External devices (particularly Modbus) often make values available as a 32 bit IEEE-754 value [1]. Previous version would give you the represented value as a possibly rounded decimal number and the same number with the increased precision It will convert a decimal number to its nearest single-precision and double-precision IEEE 754 binary floating-point number, using round-half-to-even rounding (the default IEEE rounding mode). Possible, but unlikely. The IEEE Standard for Floating-Point Arithmetic is a technical standard for floating-point arithmetic established in 1985 by the Institute of Electrical and Electronics Engineers. This converter does not work 100% accurate!. It's a lot more difficult to express floating point numbers in a form that a computer can understand. All of them are implemented according IEEE standard 754, where single is “single-precision”, double is “double-precision”, and extended has 80 bits. Furthermore, we lift these operators in order to deal with NaNs and infinities as defined by the IEEE 754 standard. Add a Solution < > & [^] … ?
