Binary and decimal values
Looking to convert to binary floating-point? Try my floating-point converter. Looking to calculate with binary numbers? Try my binary calculator. Looking to convert numbers between arbitrary bases? Try my base converter. This is a decimal to binary and binary to decimal converter. Conversion is implemented with arbitrary-precision arithmetic , which gives the converter its ability to convert numbers bigger than those that can fit in standard computer word sizes like 32 or 64 bits.
Besides the converted result, the number of digits in both the original and converted numbers is displayed. For example, when converting decimal This means that the decimal input has 2 digits in its integer part and 3 digits in its fractional part, and the binary output has 6 digits in its integer part and 3 digits in its fractional part.
Other ways include Roman Numerals , Binary , Hexadecimal , and more. You could even just draw dots on a sheet of paper! The Decimal Number System is also called "Base 10", because it is based on the number 10, with these 10 symbols:.
But notice something interesting: But you don't have to use 10 as a "Base". You could use 2 "Binary" , 16 "Hexadecimal" , or any number you want to!
Now see if it has tallied the right number of dots, as in this example using base 2. Count up until just before the "Base Number", then start at 0 again, but first you add 1 to the number on your left.
Binary Numbers are just "Base 2" instead of "Base 10". So you start counting at 0, then 1, then you run out of digits They look the same as the decimal numbers up to 9, but then there are the letters "A',"B","C","D","E","F" in place of the decimal numbers 10 to
