How to properly define the [float] data type in mysql

Question

I defined (through PHPMYADMIN) a field with the float data type.
When I try to insert a number as 78.556677099932222377 it will translate it to 79.
How do I make it to save the correct number, at least 7 places after the decimal dot?

Answer 1

Open phpMyAdmin with structure option and define the float as:

FLOAT(23,19)
