May be this is not the answer you are after but I post this just in case.. 1 10000001 10110011001100110011010. IEEE-754 Floating Point Converter, IEEE-754 Floating-Point Conversion From Decimal Floating-Point To 32-bit and 64-bit Hexadecimal Representations Along with Their Binary Equivalents. When we talk about a bias of 127, we mean that if we look at the 8-bit exponent in the 32-bit format, it's going to be 127 bigger than the actual exponent. The IEEE Standard for Floating-Point Arithmetic (IEEE 754) is a technical standard for floating-point computation which was established in 1985 by the Institute of Electrical and Electronics Engineers (IEEE).The standard addressed many problems found in the diverse floating point implementations that made them difficult to use reliably and reduced their portability. Please note there are two kinds of zero: +0 and -0. This standard specifies the single precision and double precision format.
