### howManyTimes
|
|
|
|
Returns the number of times `num` can be divided by `divisor` (integer or fractional) without getting a fractional answer.
|
|
Works for both negative and positive integers.
|
|
|
|
If `divisor` is `-1` or `1` return `Infinity`.
|
|
If `divisor` is `-0` or `0` return `0`.
|
|
Otherwise, keep dividing `num` with `divisor` and incrementing `i`, while the result is an integer.
|
|
Return the number of times the loop was executed, `i`.
|
|
|
|
```js
|
|
const howManyTimes = (num, divisor) => {
|
|
if (divisor === 1 || divisor === -1) return Infinity;
|
|
if (divisor === 0) return 0;
|
|
let i = 0;
|
|
while (Number.isInteger(num / divisor)) {
|
|
i++;
|
|
num = num / divisor;
|
|
}
|
|
return i;
|
|
};
|
|
```
|
|
|
|
```js
|
|
howManyTimes(100, 2); // 2
|
|
howManyTimes(100, 2.5); // 2
|
|
howManyTimes(100, 0); // 0
|
|
howManyTimes(100, -1); // Infinity
|
|
```
