You can use a regular expression to match the characters that appear in floating point numbers.
SELECT *
FROM yourTable
WHERE number_column RLIKE '^[-0-9.]+$'
Note that this simple regexp doesn't actually check for valid numeric syntax; it will allow 1.2.3 or 3-2. If you need a more accurate regular expression, see Regular expression for floating point numbers

You can do this:
SELECT *
FROM t
WHERE number_column <> 0 OR number_column = '0'
String to numeric comparison will convert the string to float and compare. Non-numeric strings become 0 (which you want to skip), but so does zero-ish strings. So you need to check for this case too.
