Line 5: Input a number of the form 2^a 3^b <lang fractran> {2/3} </lang> The output is 2^(a+b) Line 12: A list of no fractions does nothing, then immediately stops. <lang fractran>{}</lang> ==Integer Sequence== Given the number 1 as input the following program will, as its (3n-2)th step, produce the number 2^n. <lang fractran> {2/3, 9/2, 2/1}</lang> ==Logical operations== Line 22: <lang fractran> {5/6, 1/2, 1/3} AND gate {5/6, 5/2, 5/3} OR gate {1/22, 5/11} NOT gate (uses 11 as a halt flag, result of 2^a*11 is 5^not(a)) {1/6, 5/2, 5/3} XOR gate {1/66, 5/22, 5/33, 5/11} NAND gate (needs 11 flag) {5/66, 1/22, 1/33, 5/11} NXOR gate (needs flag) {1/66, 1/22, 1/33, 5/11} NOR gate (needs flag) so much for all the commonly encountered ones, but there's still another eight to go. Most are obscure and of limited utility. {1/2, 1/3} ZERO gate, returns false regardless of its input {1/6, 5/2, 1/3} "A and not B", true only if A is true and B is false {5/2, 1/3} A , returns the state of A regardless of B {1/6, 1/2, 5/3} "B and not A", true only if B is true and A is false {1/2, 5/3} B , returns the state of B regardless of A {1/66, 1/33, 5/11} "A or not B" (needs flag) {1/66, 1/22, 5/11} "B or not A" (needs flag) {5/66, 5/22, 5/33, 5/11} ONE gate, returns true regardless of its input, needs flag NOT A and NOT B are omitted because the one-input NOT gate is already up there. Line 48: 2^a 3^b 5^c <lang fractran> {1001/30, 143/6, 143/10, 143/15, 13/2, 13/3, 13/5} </lang> Returns 7^A 11^B 13^C where (A,B,C) are (a,b,c) in ascending order.
