I need to encode and decode IEEE 754 floats and doubles from binary in node.js to parse a network protocol. Are there any existing libraries that do this, or do I have to read the spec and implement it myself? Or should I write a C module to do it?

How can I convert a number with a decimal part to the simple precision system of the IEEE-754 in python in such a way that I enter the number and I throw the standard sign, exponent and mantissa? Example Input: 10.27 Example Output: 0 10000011 01001000101000111101011 Sign-Exponent-Mantissa. Here is my attempt to solve the problem.

If you want the byte values of the IEEE-754 representation, the struct module can do this: >>> import struct >>> f = 1.2717441261e+20 >>> struct.pack('f', f) '\xc9\x9c\xdc`' This is a string version of the bytes, which can then be converted into a string representation of the hex values:

I have been looking for a way to display the IEEE 754 format of a value contained in a Excel cell (since they are documented to work that way). I'd prefer not to rely on VBA for this project ( although I might get tempted if a memcpy -like solution is possible ).

I have to encode the electron charge, which is -1.602*10-19 C, using IEEE-754. I did it manually and verified my result using this site. So I know my representation is good. My problem is that, if I try to build a C program showing my number in scientific notation, I get the wrong number. Here is my code:

The below code is simple converting a 32bit-integer from the object being passed to the function, the 32-bit integer represents a floating number.

I was only able to convert a decimal into a binary single-precision IEEE754, using the struct.pack module, or do the opposite (float16 or float32) using numpy.frombuffer Is it possible to convert a

I have serialized 32-bit floating number using GO language function (math.Float32bits) which returns the floating point number corresponding to the IEEE 754 binary representation. This number is then serialized as 32-bit integer and is read into java script as byte array.
