Like this :

if(is_float(number))
this is float
If number variable is a string, check it using the way below.

PHP Code:
if (contain(number".") != -1)
{
  
// might be float

Note that if the number is 1.000000 then it might also be an integral value (1).
So if you read our messages you will definitely understand.
