Not

The '''not''' operator is a [[Boolean operator]] which returns {{code|literal|true}} if the argument is {{code|literal|false}} and vice versa.

Its token is named '''NOT'''.

Remember that all comparison instructions do not need a '''not''' operator because there is always another operator which complements them:
{| class="wikitable"
! A
! NOT A
|-
| [[Equal]]
| [[Not equal]]
|-
| [[Greater than]]
| [[Less than or equal]]
|-
| [[Less than]]
| [[Greater than or equal]]
|}

{{codeblock|{{code|operator|not}}{{tag|whitespace}}{{tag|value|Boolean}}}}

=== Example ===

{{codeblock|{{code|keyword|I did this as long as}}{{code|whitespace| }}{{code|operator|not}}{{code|whitespace| }}{{code|variable|Applejack}}{{code|whitespace| }}{{code|operator|is}}{{code|whitespace| }}{{code|literal|1}}{{code|punctuation|:}}

{{code|continuation|...}}}}

This loops the next part of code if variable {{code|variable|Applejack}} is not equal to {{code|literal|1}}.

This is equivalent to the following '''Java''' code:
{{codeblock|<SOURCE LANG=java>while(! (Applejack==1)) { ...</SOURCE>}}

Remember that this code is equivalent to using [[not equal]], such that:

{{codeblock|{{code|keyword|I did this as long as}}{{code|whitespace| }}{{code|variable|Applejack}}{{code|whitespace| }}{{code|operator|is not}}{{code|whitespace| }}{{code|literal|1}}{{code|punctuation|:}}}}

and to the following '''Java''' code:
{{codeblock|<SOURCE LANG=java>while(Applejack!=1) { ...</SOURCE>}}
