IEEE 754-2008 governs binary floating-point arithmetic. It specifies number formats, basic operations, conversions, and exceptional conditions. The 2008 edition supersedes both the 754-1985 standard and the related IEEE 854-1987 which generalized 754-1985 to cover decimal arithmetic as well as binary.

Floating point - Wikipedia, the free encyclopedia
In computing, floating point describes a system for numerical representation in which a string of digits (or bits) represents a rational number. The term floating point refers to the fact that the...

IEEE 754-2008 - Wikipedia, the free encyclopedia
The IEEE Standard for Floating-Point Arithmetic ( IEEE 754 ) is the most widely-used standard for floating-point computation, and is followed by many hardware (CPU and FPU) and software implementa...

This means that (for instance) a binary floating point variable can't have the exact value of decimal 0.1. Instead, if you have some code like ... An example in binary floating point is that 3.65d+0.05d != 3.7d (although it may be displayed as 3.7 in some situations).

The sign of a binary floating-point number is represented by a single bit. A 1 bit indicates a negative number, and a 0 bit indicates a positive number. ... A binary floating-point number is similar. For example, in the number +11.1011 x 23, the sign is positive, the mantissa is 11.1011, and the exponent is 3.

This is how I read it: For (1), the fraction can be read as 1 divided by 21, where 1 is the amount of binary digits to the right of the decimal point. For (2), the fraction can be read as 7 divided by 23. There are 3 digits to the right...

Thread Subject: decoding floating point binary data from an HP impedance analyzer ... Hello Mikael, If the 32-bit binary data floating point format you describe is actually in IEEE 754 standard format, then I would suspect your problem is simply a "big-endian" versus "little-endian" confusion. Your four bytes...
