Have a text box which get data for price.
If someone enter something like “3.” i want to get it converted to “3.0”
i cannot append “0” simply in the end because then if it is “100” gets converted to “1000”

Also is_numeric(“3.”) returns 1.

Whats the possible way round?

    You need number_format():

    number_format('3', 1, '.', ''); // = 3.0
number_format('3.', 1, '.', ''); // = 3.0
number_format('3.22', 1, '.', ''); // = 3.2
number_format('3.22abc', 1, '.', ''); // = 3.2 and a "PHP Notice:  A non well formed numeric value encountered"
number_format('abc3.22', 1, '.', ''); // = "PHP Warning:  number_format() expects parameter 1 to be double, string given"
