What's the difference between a single precision and double precision floating point operation?

Question

What is the difference between a single precision floating point operation and double precision floating operation?

I\'m especially interested in practical terms in

Answer 1

Single precision number uses 32 bits, with the MSB being sign bit, whereas double precision number uses 64bits, MSB being sign bit

Single precision

SEEEEEEEEFFFFFFFFFFFFFFFFFFFFFFF.(SIGN+EXPONENT+SIGNIFICAND)

Double precision:

SEEEEEEEEEEEFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF.(SIGN+EXPONENT+SIGNIFICAND)
