(CS417/517) Homework 1 Homework 1. (15 points) Consider a miniature binary computer whose floating-point words consist of 4 binary (i.e., base-2) digits for the mantissa and 3 binary digits for the exponent (plus sign bits). Let x=(.1011)220,y=(.1100)220. Mark in the provided table whether the machine operation indicated (with the result Z assumed normalized) is exact, rounded (i.e., subject to nonzero rounding error), overflows, or underflows.
