v01-l1-precision

What's the main difference between double and float type ?

double is a long integer while float is a floating point number

no differences, it's just two aliases to define a floating point number

double uses double precision arithmetic, while float uses only single precision

double represents a pair of two float variables

???

See the first lecture :

// Single precision floating point number (Please DO NOT USE it !)
float x {3.1415927};
// Double precision floating point number
double y {3.141592653589793};

Don't forget that it's strongly recommended to use double as default type when manipulating floating point numbers ...
