I am trying to make a rounding function that rounds to the nearest hundred, but when I tried it, it only outputs 0.

```
int roundrl() {
rl = 200;
if (rl < 100, rl > -1) {
rl = 0;
} else if (rl < 200, rl >99) {
rl = 100;
} else if (rl < 300, rl > 199) {
rl = 200;
} else if (rl < 400, rl > 299) {
rl = 300;
} else if (rl < 500, rl > 399) {
rl = 400;
} else if (rl < 600, rl > 499) {
rl = 500;
} else if (rl < 700, rl > 599) {
rl = 600;
} else if (rl < 800, rl > 699) {
rl = 700;
} else if (rl < 900, rl > 799) {
rl = 800;
} else if (rl < 1000, rl > 899) {
rl = 900;
} else if (rl < 1100, rl > 999) {
rl = 1000;
}
}
```

What each else if is meant to do is to check if rl is below a number and above another.
