Question

diffrence between single and double calculation​

Answer 1

The IEEE Standard for Floating-Point Arithmetic is the common convention for representing numbers in binary on computers. In double-precision format, each number takes up 64 bits. Single-precision format uses 32 bits, while half-precision is just 16 bits.

Answer 2

Single circulation
Double circulation
Blood flows only once through the heart during one cycle of passage through the body.
Blood flows twice through the heart during one cycle of passage through the body.
Occurs only in fishes.
Occurs in all other vertebrates other than fishes.
Only venous blood passes through the heart
Mixed or oxygenated or venous blood passes through the heart.
Less efficient as gill capillaries slow down the blood flow, hence the body receives blood at a low pressure which decreases the rate of oxygen supply to the cells.
More efficient as blood flows at higher pressure especially in birds and mammals. This increases the rate of supply of food and oxygen to the cell and also rapid removal of wastes from them.
