Web11 sep. 2024 · idiv executes signed division. idiv divides a 16-, 32-, or 64-bit register value (dividend) by a register or memory byte, word, or long (divisor). What is Div and IDIV? DIV – Divides an unsigned dividend by an unsigned divisor. DIV treats a . leftmost 1-bit as a data, not a minus sign. • IDIV – Divides a signed dividend by a signed divisor . WebThe IDIV (signed divide) instruction performs signed integer division, using the same operands as the DIV instruction. For both DIV and IDIV, all of the arithmetic status flags are undefined after the operation. When doing 8-bit division, you must sign-extend the dividend into AH before using IDIV . For example, (-48/5) :
