An integer is a form of text which you tell a computer to do but it is just full numbers like: 1,2 and 3. But it only uses numbers without speech marks around them.
A float is a form of text but it only includes decimal numbers and no speech mark around the text. e.g. 1.1 and 1.2 ect.
As well as float and integers there is another form of text called String which uses numbers and letters and it also need speech marks to go around the text for it to be a form of string here is an example "Tommy".
