What is the difference between float data type and double data type ?

A float is a 32 bit IEEE 754 floating point.
A double is a 64 bit IEEE 754 floating point.
so it is just a matter of precision because neither of the fraction portions .2 and .26 have a terminating binary representation, so there is some rounding error.
the double has more precision so it has slightly less rounding error.
