Keep right operand within width when right shiftingHEADmaster
NUM_IN_PAGE could return a value much larger than 64. According to the C11 spec 6.5.7 paragraph 3 this is undefined behavior: > If the value of the right operand is negative or is greater than or > equal to the width of the promoted left operand, the behavior is > undefined. On most platforms, this is usually not a problem as the architecture will mask off all out-of-range bits.
