When aligning selected objects in InDesign, you can nudge them by pressing the arrow keys. In some cases it can be impossible to use the arrow keys to align two objects when either object’s position is a fractional unit, such as an X position of 124.582 points. If the second object is positioned at 124 or 124.839 points, nudging it won’t line it up with 124.582 points because each arrow key nudge is one whole point from its original position.

If you just want the two objects to line up and you don’t care what the numbers are, select both objects and use the align buttons, which you can find on the Align palette and the Control palette. If you want to get rid of the fractional units, try these other two methods:

Enable View > Snap to Grid if you want them to nudge to grid increments.

If you want to nudge by single whole units using arrow keys, first click in the X or Y field in the Control palette, and then press the up arrow and down arrow keys. When a field is active in the Control palette, nudging snaps the field’s value to the nearest whole number. This makes it easy to nudge object after object to the same exact position.
