What is floating-point operation?

Floating-point operation is real number operation, because computers can only store integers, so real numbers are divisors, so floating-point operation is slow and there will be errors. At present, most machines are 32-bit, that is, if all 32 bits are used to represent integers, it is 0 to 2 32-1for unsigned integers and-2 31for signed integers.

Floating-point operations use three different kinds of data:

1) integer, divided into words, short integers and long integers.

2) True, single precision and double precision.

3) compressed binary number (BCD)
