pub enum Token {
    Num(f64),
    Band(usize),
    Add,
    Sub,
    Mul,
    Div,
    Neg,
}

RPN token. Band(i) is 0-indexed (source b1 → Band(0)).

Variants

Add

Add the two preceding operands.

Sub

Subtract the right operand from the left operand.

Mul

Div

Divide the left operand by the right operand.

Neg

Negate the preceding operand.
