What does 'double' mean ? (ex: double x=3.14)

Question

Answer 1

float is represented in 32 bits, with 1 sign bit, 8 bits of exponent, and 23 bits of the significand (or what follows from a scientific-notation number: 2.33728*1012; 33728 is the significand).
double is represented in 64 bits, with 1 sign bit, 11 bits of exponent, and 52 bits of significand.
basically double is more precise than float
