Edit: According to the Section 6.5.7 of the latest draft standard, this behavior on negative numbers is implementation dependent:The result of E1 >> E2 is E1 right-shifted E2 bit positions.
WebJul 27, 2014 · Dividing by some number of bits with rounding toward zero results in something like 0x007FFFFF for e.g. y=8 . (Rounding toward zero results in the same behavior for positive and negative.) Input x=0x007FFFFF, y=8 results in 0x7FFFFF00, which is valid. Input x=0x00800000, y=8 -- x being one higher--results in 0x80000000, which has … WebArithmetic right shifts for negative numbers in N−1's complement (usually two's complement) is roughly equivalent to division by a power of the radix (usually 2), where …
