Single precision number is a way to express approximate value of real number by computer. In VB, the single variable is stored in the form of IEEE 32-bit (4-byte) floating-point value. Its range is from - 3.402823e38 to - 1.401298e-45 when the number is negative, and from 1.401298e-45 to 3.402823e38 when the number is positive

floating point operation is real number operation, because the computer can only store integers, so real numbers are divisors, so floating point operation is very slow and there will be errors. Now most machines are 32-bit, that is to say, if 32 bits are used to represent integers, then it is 0 to 2 ^ 32-1 for unsigned integers and - 2 ^ 31 to 2 ^ 31-1 for signed integers
