Float Comparisons

I am having an issue where comparing two floats seems to return nonsensical results. I have two floats, mid and curHeight, than I am comparing to each other. See below:

Code (CSharp):

1.  Debug.Log("pre gravity " + "mid" + mid.ToString("F32") + "  curheight" + curHeight.ToString("F32"));
2.         if (mid < curHeight)
3.         {
4.             Debug.Log("applying gravity");
5.             timeInAir += 1 * Time.deltaTime;
6.             verticalHeight -= gravity * Time.deltaTime;
7.         }

How can it be possible that the mid variable can be less than the curHeight float when they are evidently the same? I have well surpassed the digits of accuracy that a float provides here. Moreover, why is it only seen as less than some of the time and not others? 3 of the 567 times true must have been returned, despite the fact the other 564 times the same value was compared.

I have been rather stumped on this for a while, any help would be appreciated. I am happy to answer any questions and provide more information if it is required.

Thanks in advance

 

Hmm yes float comparison... a large topic on google about it but you could first compare them with this maybe?

I believe this has worked, though part of me is still frustrated that values that show as equivalent are not treated as equivalent! Thanks for the help
