WebMar 28, 2013 · This method fails when 1) float is not IEEE 754 32 bit binary (not so rare) 2) unsigned is 16-bit (common in embedded world) 3) endian of unsigned/float do not match. (rare). 4) Mathematical interpretation is used for exponent/mantissa as this answer shows the biased exponent and the incomplete significand/mantissa. – chux - Reinstate Monica The IEEE 754 standard specifies a binary32 as having: • Sign bit: 1 bit • Exponent width: 8 bits • Significand precision: 24 bits (23 explicitly stored)
WebOct 28, 2016 · IEEE-754 defines standards for multiple floating-point types. For many years, they were all binary floating point; that's what Java's float and double are: float is a 32-bit IEEE-754 binary floating point value (what the standard calls binary32 ). double is a 64-bit one (what the standard calls binary64 ). WebNov 6, 2013 · It seems that the IEEE 754 standard defines 16,777,214 32-bit floating point values as NaNs, or 0.4% of all possible values.
