سوال ۲۴ کنکور ارشد علوم کامپیوتر ۱۴۰۱

PASSAGE 2 (last paragraph)

Thus all significand values are approximations regardless of magnitude, although values beyond the capacity of the significand are approximated less accurately than those within. It should be noted that floating-point numbers represented as binary-coded-decimal numbers are not subject to the conversion errors discussed above. The significand is shifted left or right (toward the radix point) with appropriate adjustment of the exrad value, until the leftmost or rightmost element (in terms of the number base of the exrad) is nonzero in a process known as normalization. Whereas the maximum magnitude of a floating-point quantity is controlled by the length and coding scheme of the exrad, the precision or accuracy of a quantity is controlled by the effective length of the significand.
