Answer 1

A Float is expressed a number as fractional value as 1.00, 2.00, 3.00, 1.5, 1.50, 1.75, 1.83, 1.333333333333 etc.

An integer means full value,it has no fraction,so it's expressed as 1, 2, 3, 4, 5, 6, 7 8, ...100 etc.

A integer can convert into float and this float is expressed as 1 to 1.0, or 1.00

A float can convert into integer by omitting It's fractional part as 1.333333 to 1, 2.75 to 2

A floating point number is a extension of an older format ,called fixed point numbers.A fixed point number. would store a fixed number of digits before and after the decimal point (in binary).for example ,+1110101.00001000 is an example of a 16 bit fixed point number in 7.8 format(one bit is spent on sign).
The term double is short for "double precision floating point number ".it literally means that twice as many as bits are used in storing it as a regular floating point number.on a typical modern machines,floats are 32 bits( 1 but for sign,8bits for exponent,23 bits for value),while doubles are 64 bits(1 for the sign,11 bits for exponent and 52 bits for the value).
