Double is also like floating point but having size of 4 bytes,double has 8 bytes,long double has 10 bytes and integer has 2 bytes.So long double can store larger floating points also.Here 3.14 is a long double.

A floating-point constant without an f, F, l, or L suffix has type double. If the letter f or F is the suffix, the constant has type float. If suffixed by the letter l or L, it has type long double.

The double is used for floating 44.45, int for integers like 2,567etc , long double for large floating values like 6.98765342 .

double :%lf
float:%f or %e or %g
int :%i or %d
long int:%ld or %li
unsigned long:%lu
unsigned int:%u
