A double is an IEEE754 double-precision floating point number, similar to a float but with a larger range and precision. IEEE754 single precision numbers have 32 bits (1 sign, 8 exponent and 23 mantissa bits) while double precision numbers have 64 bits (1 sign, 11 exponent and 52 mantissa bits).
The heart muscle, like every other organ or tissue in your body, needs oxygen-rich blood to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation. The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle. The right coronary artery supplies blood mainly to the right side of the heart.
  The aorta is the largest blood vessel in the body, originating from the left ventricle of the heart and bringing oxygenated blood to all parts of the body in the systemic circulation. The aorta is the main (largest) artery of the circulatory system.It carries the blood from the heart to all prats of the body.n aortic thrombus is a blood clot in the aorta. This would be a bad situation because a clot that breaks free in the aorta can cause tissue death in any organ of the body. Th â¦ is can result in anything from a stroke, heart attack, or kidney failure.
