### howManyTimes
Returns the number of times `num` can be divided by `divisor` without getting a fractional answer. Works for both negative and positive integers.`divisor` can be fractional too.
If `divisor` is `-1` or `1` returns `Infinity`.
If `divisor` is `-0` or `0` returns `0`.
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
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); //2
