Finding covered distance of a gameobject

I am trying to check if a platform has reached a specific distance relative to its starting/original position. For achieving this objective I used the following code snippet but it doesn't seem to work.

 float maxMoveValue = 10;
 float originalXpos = transform.position.x;

         if(transform.position.y == originalYpos + maxMoveValue)
         {
             maxVertical = true;
         }

I have also tried it this way:

  Vector3 originalVector = new Vector3(originalXpos + maxMoveValue, 0f, 0f);
        if(Vector3.Distance(transform.position, originalVector) ==0 )
         {
             maxHorizontal = true;
         }

But this also doesn't work.

What am I doing wrong?

EDIT:

I have found the culprit but don't know why is this happening and what can be the solutioin?

Problem:

Actually the float addition is not working properly. if a = 22.3519; & b = 10; result = a +b; is resul = 22.35190
