I need to represent an IEEE 754-1985 double (64-bit) floating point number in a human-readable textual form, with the condition that the textual form can be parsed back into exactly the same (bit-wise) number.

Is this possible/practical to do without just printing the raw bytes? If yes, code to do this would be much appreciated.

How do you convert from IEEE 754 single-precision floating-point format to decimal?

as seen on Stack Overflow - Search for 'Stack Overflow'
I understand that the first bit is the sign and that the next 8 bits is the exponent. So in this example you would have 1.1001*2^-4 ? How do I then interpret this in decimal? 0 01111011 10010000000000000000000 >>> More

So, title says it all. Why are floating point values so prolific in computer programming. Due to problems like rounding errors, and not being able to even accurately represent numbers such as 0.1, I really can't see how they got as far as they did. I understand that the computation is faster… >>> More
