The decimal number consists of a total of 10 numeric characters in 0~9, 10 in each of the decimal digits, and a maximum number of 9 in each decimal digit.The binary number consists of 0 and 12 numeric characters, and in binary one, the maximum
1. 10 -----> 2(10, 25.625) (10) Integer: 25/2 = 12 ...... 1 12/2 = 6... 0 6/2 = 3... 0 3/2 = 1... 1 1/2 = 0... 1 Then we write the remainder in the order from bottom to bottom: 11001, then this 11001 is the binary form of decimal 25 Decimal part: 0.6
We know that when dealing with some floating-point numbers, the operation produces an error, resulting in a similar infinite loop.Example: @Test publicvoid Demo () { double a1=2.0; double a2=1.1; SYSTEM.OUT.PRINTLN (A2-
