Webb26 jan. 2024 · Add one more to that and you get a 54-bit integer that is a 1 followed by 52 0's followed by a 1. This is not representable exactly in IEEE double because of the 53-bit mantissa limitation. So the smallest integer number that cannot be represented exactly in IEEE double is the 54-bit binary integer 100...001, which is decimal. 2^53+1. A floating-point number consists of two fixed-point components, whose range depends exclusively on the number of bits or digits in their representation. Whereas components linearly depend on their range, the floating-point range linearly depends on the significand range and exponentially on the range of exponent component, which attaches outstandingly wider range to the number. On a typical computer system, a double-precision (64-bit) binary floating-point number has a coef…

The sign is positive. The biased exponent is 1101 = 13, so the actual exponent is 13 − 127 = − 114, assuming single precision. So the answer you have is correct: 2 − 114 × ( 1.101 1001 1111 1110 1101 0011) 2. Share.
