# Negator

Library: | Arithmetic
Introduced: | 2.0 Beta 22
Appearance: |

## Behavior

Computes the two's-complement negation of the input. This negation is performed by maintaining all the lower-order bits up to the lowest-order 1, and complementing all bits above that.

If the value to be negated happens to be the least negative value, then its negation (which cannot be represented in two's-complement form), is still the least negative value.

## Pins

West edge (input, bit width matches Data Bits attribute)
  The value to negate.
East edge, labeled -x (output, bit width matches Data Bits attribute)
  The negation of the input. If the input happens to be the least negative value representable in dataBits bits, however, then the output matches the input.

## Attributes

When the component is selected or being added, Alt-0 through Alt-9 alter its Data Bits attribute.

Data Bits
  The bit width of the component's input and output.

## Poke Tool Behavior

None.

## Text Tool Behavior

None.
