IDIV - Signed Integer Division
Usage: IDIV src
Modifies flags: (AF,CF,OF,PF,SF,ZF undefined)
Signed binary division of accumulator by source. If source is a byte value, AX is divided by "src" and the quotient is stored in AL and the remainder in AH. If source is a word value, DX:AX is divided by "src", and the quotient is stored in AL and the remainder in DX.
Taken from "Intel Opcodes and Mnemonics"
DX:AX是什么意思?
非常感谢您的时间:)
最佳答案
这是一对寄存器:DX
和AX
。
分子本身是一个双字。分子的高位字应存储在DX
中,低位字应存储在AX
中。
