Decimal 50, converted to binary value is 110010.
Specific algorithm: 50/2=25 more than 0, 25/2=12 more than 1, 12/2=6 more than 0, 6/2=3 more than 0, 3/2=1 more than 1,1 /2=0 more than 1. Arrange the remainders in reverse order and the result is a binary number.
1. Convert decimal integer to binary integer:
Convert decimal integer to binary integer using the method of "divide by 2, take remainder, and arrange in reverse order".
The specific method is: divide the decimal integer by 2, you can get a quotient and remainder; then use 2 to divide the quotient, you will get a quotient and remainder, and so on, until the quotient is less than 1, and then The remainder obtained first is used as the low-significant bit of the binary number, and the remainder obtained later is used as the high-significant bit of the binary number, and they are arranged in sequence.
2. Convert decimals to binary decimals:
Convert decimals to binary decimals using the "multiplied by 2, rounded, and arranged in order" method. The specific method is: multiply the decimal number by 2 to get the product, take out the integer part of the product, then multiply the remaining decimal part by 2 to get another product, then take out the integer part of the product, and so on until the The decimal part is zero, and 0 or 1 is the last bit of binary. Or until the required accuracy is achieved.
Then arrange the extracted integer parts in order. The integer taken first is used as the high-order significant bit of the binary decimal, and the integer taken later is used as the low-order significant bit.
For example: 0.625=(0.101)B
0.625*2=1.25, take out the integer part 1;
0.25*2=0.5, take out the integer part 0;
0.5*2=1, take out the integer part 1.
