I wanna take a float with unknown number of decimals and change it into a integer by multiplying it by 10 until it's an integer, and i know it has to be done with a loop but I can't figure out how.
take 216.612 for example, it should be converted to 216612 at the end.

    Does this answer your question (looks like an almost exact duplicate - even using a very similar number)? [printing the double number wrongly](https://stackoverflow.com/questions/65026826/printing-the-double-number-wrongly) – Adrian Mole Dec 01 '20 at 17:48
  • Convert to a string using `sprintf()`, using string techniques remove the decimal point, convert the remaining string back to `int` via `strtol()`. – ryyker Dec 01 '20 at 17:49
  • More likely than not, your implementation stores floating points in the IEEE-754 format. In that format `216.612` does not have an exact representation, so the moment you store that number in a variable it's no longer *exactly* `216.612`, so no *exact* conversion can revert it to `216.612`. It becomes possible once you allow for tolerances, but in that case you have to decide in advance what precision you require. – dxiv Dec 01 '20 at 17:51

  • Thanks all a lot, I searched but I didn't see the other question – Alireza Mirzaei Dec 01 '20 at 18:05
