Is floating point multiplication associative
WebThe resulting floating-point numbers are almost always in normalized floating-point forms. Since the arithmetic is erroneous (inexact), the computed result always contains noise. Consequently, the floating-point addition and multiplication are only commutative; both the associative and distributive laws do not hold. WebOct 1, 1996 · A normalized radix 10 floating-point number has its decimal point just to the left of the first non-zero digit in the mantissa. The normalized floating-point representation of -5 is -1 * 0.5 * 10 1 .
