}function insistWithinBounds(num, canvasSize) {
Nat(num);

// 0 to canvasSize - 1
insist(num >= 0 && num < canvasSize)`\

} divide: (x, y) => Nat(Math.floor(x / y)),
}); add: (x, y) => Nat(x + y),
subtract: (x, y) => Nat(x - y), with: (left, right) => Nat(left + right),
without: (whole, part) => Nat(whole - part),function getPixelColor(x, y) {
const rawPixel = harden({ x: Nat(x), y: Nat(y) });
return state[rawPixel.x][rawPixel.y];
} multiply: (x, y) => Nat(x * y),
divide: (x, y) => Nat(Math.floor(x / y)),@agoric/nat
Ensures that a number is within the natural numbers (0, 1, 2...) or throws a RangeError
