EXACT VERSUS INEXACT DECIMAL FLOATING-POINT NUMBERS AND ARITHMETIC

Exact Versus Inexact Decimal Floating-Point Numbers and Arithmetic

The IEEE 754 standard does not distinguish between exact and inexact floating-point numbers.There is no bit or field in the binary encoding that indicates whether a floating-point number is exact or not.This is the case for binary and decimal floats.An inexact operation raises an inexact flag in a floating-point status register.The inexact result i
