Double cell integer manipulating extra words.
Words definition table columns:
- Name: A name of a word with optional parameters.
- Imm.: Immediate - if a word is executed even if we are in the compilation mode.
- Mode: I = interpretation mode only (not available during compilation), C = compilation mode only (not available during interpretation), IC = available in both modes.
- Description: A word name, followed by the stack diagram - () = data stack, [] = return stack, {} = object stack - and description of the word itself.
| Name | Imm. | Mode | Description |
|---|---|---|---|
| 2ROT | no | IC | Double rotate (n1 n2 n3 n4 n5 n6 -- n3 n4 n5 n6 n1 n2) Rotate the third pair on the stack to the top of the stack, moving down the first and the second pair. |
| Name | Imm. | Mode | Description |
|---|---|---|---|
| >DOUBLE | no | IC | String to number ( -- d true | false) {s -- } Parses a string into a double cell integer. Leaves true and the number on the stack, if the conversion was successfull. Leaves just false, if the conversion failed. |
| D* | no | IC | d3 = d1 * d2 (d1 d2 -- d3) Multiplies d1 and d2 and leaves the product on the stack. |
| D/ | no | IC | d3 = d1 / d2 (d1 d2 -- d3) Divides d1 by d2 and leaves the quotient on the stack. |
| D<= | no | IC | Less than or equal (d1 d2 -- flag) Returns -1 if d1 <= d2, 0 otherwise. |
| D<> | no | IC | Not equal (d1 d2 -- flag) Returns -1 if d1 is not equal to d2, 0 otherwise. |
| D> | no | IC | Greater than (d1 d2 -- flag) Returns -1 if d1 > d2, 0 otherwise. |
| D>= | no | IC | Greater than or equal (d1 d2 -- flag) Returns -1 if d1 >= d2, 0 otherwise. |
| D0<> | no | IC | Nonzero (d1 -- flag) Returns -1 if d1 is not equal to 0, 0 otherwise. |
| D0> | no | IC | Greater than zero (d1 -- flag) Returns -1 if d1 is greater than 0, 0 otherwise. |
| D1+ | no | IC | Add one (d1 -- d2) Adds one to the top of the stack. |
| D1- | no | IC | Subtract one (d1 -- d2) Substracts one from the top of the stack. |
| D2+ | no | IC | Add two (d1 -- d2) Adds two to the top of the stack. |
| D2- | no | IC | Subtract two (d1 -- d2) Substracts two from the top of the stack. |
| DAND | no | IC | Bitwise and (d1 d2 -- d3) Stores the bitwise AND of d1 and n2 on the stack. |
| DMOD | no | IC | Modulus (remainder) (d1 d2 -- d3) The remainder when d1 is divided by d2 is left on the top of the stack. |
| D/MOD | no | IC | d3 = d1 mod d2, d4 = d1 / d2 (d1 d2 -- d3 d4) Divides d1 by d2 and leaves quotient on top of stack, remainder as next on stack. |
| DNOT | no | IC | Bitwise not (d1 -- d2) Inverts the bits in the value on the top of the stack. This performs logical negation for truth values of −1 (True) and 0 (False). |
| DOR | no | IC | Bitwise or (d1 d2 -- d3) Stores the bitwise or of d1 and d2 on the stack. |
| DXOR | no | IC | Bitwise exclusive or (d1 d2 -- d3) Stores the bitwise exclusive or of d1 and d2 on the stack. |
