Produces

Twig: [%cndt p=twig q=twig]

Sample

p and q are twigs.

Tall form

    q

Wide form

%.(p q)

Irregular form

None

Examples

/~zod/try=> (dec 42)
41
~zod/try=> %.(42 dec)
41

In the most straightforward case %. allows us to reverse the order of arm and arguments.

/~zod/try=> %.
              %+  add
                %+  mul  2  20
              2
            dec
41

Here we add 2 to the product of 2 and 20, and use %. to decrement our result. As you can see, %. is most useful for code organization, when you need to compute intermediate products for your final result.

Equivalent to

%-(q p)
