In C, the following 6 operators are bitwise operators (work at bit-level) The & (bitwise AND) in C or C++ takes two numbers as operands and does AND on every bit of two numbers. 没有解释思路,因为基本都是看题目要求用几个符号凑凑就好了,除了leftBitCount这个写了好久。虽然是上学期的实验,但是我依然记得这个leftBitCount,好不容易测试对了吧结果符号数超了一个,但是看来看去也是最简版本了,为了减一个符号磕了好久。 bitXor /* * bitXor - x^y using only ~ and & * Example. 3 20 isLess(x, y) Return 1 if x < y 3 24 isAsciiDigit(x) Return 1 if 0x30 <= x <= 0x39 (ASCII codes for characters '0' to '9') 3 15 trueThreeFourth(x) Multiplies by 3/4, rounding toward 0.

" Many of these puzzles are quite artificial, but you'll find yourself think. floatDigit2Float is similar to floatUChar2Float from the project. satMul2(x) Multiplies by 2, saturating to Tmin or Tmax if overflow. IntroductionThe purpose of this assignment is to become more familiar with bit-level representations of integers and floating point numbers.

You should probably save it for last, unless you've found the rest of the project too easy. satMul2(x) Multiplies by 2, saturating to Tmin or Tmax if overflow. 3: 20: isGreater(x,y) If x>y then return 1, else return 0. Correctness points. * satMul2 - multiplies by 2, saturating to Tmin or Tmax if overflow * Examples: satMul2(0x30000000) = 0x60000000 * satMul2(0x40000000) = 0x7FFFFFFF (saturate to TMax).

This page shows the operator counts for the students who have submitted entries to the Data Lab "Beat the Prof" contest. Also consider how to tell if overflow occurred. satMul2(x) Multiplies by 2, saturating to Tmin or Tmax if overflow 3 20 Table 2: Arithmetic Functions 14 Performance points. This can be accomplished by taking the int holding the sign bit, e. If the value overflows then saturate it by returning Tmin or Tmax instead. isPositive.
