command neg operand
The Neg instruction performs a Two's Complement Negation. Negating positive operand becomes negative. Negating negative operand becomes positive. Zero remains zero. The two's complement of a number behaves like the negative of the original number.
The CF flag set to 0 if the source operand is 0; otherwise it is set to 1. The OF, SF, ZF, AF, and PF flags are set according to the result.
Operand = -Operand
Replaces the value of operand (the destination operand) with its two's complement. (This operation is equivalent to subtracting the operand from 0.) The destination operand is located in a general-purpose register or a memory location.
