## Float to String Conversion - JS

javascript number to string format

parseint javascript

how can you convert the string of any base to integer in javascript

javascript float precision

javascript decimal

converting into string in js

typescript convert number to string

So I am currently working on that function

const countSixes = n => { if (n === 0) return 0; else if (n === 1) return 1; else n = (countSixes(n-1) + countSixes(n-2)) / 2; return n; }

And so my question is how to convert the final floating-point value into a string?

Every time after calling the function and trying to convert the float number it returns NaN

##### What I've Tried

- "" + value
- String(value)
- value.toString()
- value.toFixed(2)

Hope to get the answer

Thank you!

The first option works for me

<script> const countSixes = n => { if (n === 0) return 0; else if (n === 1) return 1; else n = (countSixes(n-1) + countSixes(n-2)) / 2; return n; } alert(countSixes(12) + "") </script>

**JavaScript parseFloat() Function,** Definition and Usage. The parseFloat() function parses a string and returns a floating point number. This function determines if the first character in the specified The parseFloat() function parses a string and returns a floating point number. This function determines if the first character in the specified string is a number. If it is, it parses the string until it reaches the end of the number, and returns the number as a number, not as a string. Note: Only the first number in the string is returned!

The problem is really interesting. Its `return`

`NaN`

because when you return `n`

as `String`

, as the `function`

is called recursively so it cannot perform arithmetic operations in next level.
It will never end for certain numbers like `55`

function countSixes(n,firstTime=true){ if (n === 0) return 0; else if (n === 1) return 1; else n = (countSixes(n-1,false) + countSixes(n-2,false)) / 2; if(firstTime) return n.toFixed(10); // return string else return parseFloat(n.toFixed(10)); // return float }

##### Comments

- what value do you expect? please add an example.
- I copied your function exactly as posted, ran it in the chrome console and added a toString() at the end of the call and got a string output, what value are you calling this function with?
- Each of those should work , can you give a larger example and explain what you want and what happens instead?
- Issue is you are using it in recursive manner so you probably were using inside the function call so you were subtracting strings? Hard to tell since you did not show how you were converting it to a string.
- I would define
`countSixes()`

as entry and`countSixesHelper()`

as recursive part. - I would also do that but i posted this in hurry
