lneg

negate a long

Jasmin Syntax

     lneg 

Stack

Before	After
value-word1	result-word1
value-word2	result-word2
...	...

Description

Removes the top long integer from the operand stack, negates it, and pushes the negated result back onto the stack. This is the same as multiplying the long integer by -1, which is the same as (~value) + 1.

Bytecode

Type	Description
u1	lneg opcode = 0x75 (117)

ineg, fneg, dneg

Notes

Because of the two's-complement representation used for negative numbers, negating Long.MIN_VALUE actually produces Long.MIN_VALUE, not Long.MAX_VALUE as you might expect.
