The reaction of calcium with water is less violent. SO, the heat released is not sufficient for the hydrogen to catch fire. Calcium starts floating because the bubbles of hydrogen gas which are formed during the reaction stick to the surface of the metal and hence calcium floats on water.

When calcium metal reacts with water, it is floating because the released hydrogen sticks to its surface.
Ca + H₂O ⇒ Ca(OH)₂ + H₂
As the above reaction takes place, hydrogen is released.
It sticks to the surface of the calcium metal and thus makes it float.
Hope this helps.
