Trigfunge

Trigfunge is a fungeoid invented by User:None1 that uses a queue instead of a stack and uses trigonometric functions to manipulate data.
Memory
Trigfunge uses a queue which stores unbounded floats with infinite precision.
Commands
@^v<>|_0: The same as Befunge.sct: Change queue front to sin/cos/tan(queue front) respectively.=: The next command is skipped unless the queue front is equal to the value behind it.!: Pop queue front and push it into the queue back.,: Input number and push it into queue. (optional).: Output queue front without popping it. (optional)
Computational class
Turing-complete because it can simulate a 2-register minsky machine. We can use cosn(0) (0 applied by cos n times) to represent the integer n.
We can push 3 numbers a,b,c into the queue. Then, we can use the ! command to access any number and compare any two. Decrement can be done by incrementing c instead.
