we cannot create floats

Question

In the float chapter its written we cannot create floats by adding zero or performing calculations. but when I typed 4.0 the answer was 4.0 so it was float. so what is it really.

Answer 1

The text I believe is closest to your question reads:

"They can be created directly by entering a number with a decimal point... Extra zeros at the number's end are ignored."

To me, the meaning is different than your question. Am I missing something, like a translator / language issue?

Answer 2

yes floats are general the numbers represented after decimal places. examples
12.0,123.345.

Answer 3

we can create floats

Answer 4

no in general after decimal point zeros can be neglected but in case of any programming languages. because some amount of pre memory space is allocated for it . as the program lang are case sensitive we should follow few basic rules to know more about that.
