In the table below, a number (n) in parentheses indicates that the function in question is equivalent to the constant function `n˙`, and should be inverted accordingly (check that the argument matches `n`, then return it). +The following cases of Self/Swap must be supported. | Fn | 1 | 2 |------|-------|------- | `+˜` | `÷⟜2` | `+⁼` -| `-˜` | (0) | `+` +| `-˜` | | `+` | `ט` | `√` | `×⁼` -| `÷˜` | (1) | `×` +| `÷˜` | | `×` | `⋆˜` | | `√` | `√˜` | | `÷⋆⁼` | `∧˜` | `√` | `∧⁼` | `∨˜` | `√⌾¬` | `∨⁼` -| `¬˜` | (1) | `+-1˙` +| `¬˜` | | `+-1˙` Inverses of other modifiers and derived functions or modifiers obtained from them are given below. Here the "inverse" of a modifier is another modifier that, if applied to the same operands as the original operator, gives its inverse function.
