Input Settings
Specify the character to split the input binary numbers.
Output Format
Add a binary prefix or postfix to the number.
Display binary number's decimal value next to it.
Binary Running Sum
If multiple numbers are being summed, then output their partial sum.
This utility calculates the sum of binary numbers in your browser. You can input as many binary numbers as you like. By default, numbers can be entered one per line but if your numbers are separated by another symbol, then you can adjust it in the input settings options. The input numbers can be of any length but they can only contain 0's and 1's. The length of the output sum can be changed via the output padding option. You can also add a binary prefix or postfix indicator to the output number and display the decimal value of the binary number in parentheses next to it. If you're adding several binary numbers at once, you can use the option that displays their progressive summation. Simple and easy!
Binary adder examples Click to use
This example adds together two nine-digit binary numbers. The result overflows and you get a ten-digit number as their sum.

Sum Many Binary Numbers
This example calculates the sum of a bunch of binary numbers. They are entered as a comma-separated list, so we adjust the input delimiter to be the comma character. We also set the desired output length to be 8 and add a lowercase binary prefix "0b" before the output.
0001, 0001, 0001, 0001, 0001, 0001, 0001, 0001

Running Binary Sum
In this example, we wanted to see how the sum progresses as we sum the first ten binary numbers. To do that, we activated the option "Print Running Sum", which displays all partial sums of the addition process as it happens. As you can see, the first partial sum is 1, the second is 3 (1+2), the third is 6 (1+2+3), etc. We also specified the output padding length of 10, added a subscript binary postfix "₂", and printed decimal values next to binary numbers so that we knew what was happening at each step.
1 10 11 100 101 110 111 1000 1001 1010
0000000001₂ (1) 0000000011₂ (3) 0000000110₂ (6) 0000001010₂ (10) 0000001111₂ (15) 0000010101₂ (21) 0000011100₂ (28) 0000100100₂ (36) 0000101101₂ (45) 0000110111₂ (55)
