Each hexadecimal operand is parsed to a decimal integer with parseInt(value, 16), the selected operation is applied, and the result is converted back to uppercase hex plus its decimal and binary equivalents. Division reports an integer quotient and remainder.
FAQ
Frequently asked questions
What is a hexadecimal number?
Hexadecimal (base 16) is a number system that uses sixteen symbols: 0–9 and A–F. Each hex digit represents four binary bits, making it a compact way to express binary values.
How does the hex calculator add or subtract?
The tool parses each hexadecimal input into a decimal integer, performs the chosen operation, and converts the result back to uppercase hexadecimal, along with decimal and binary equivalents.
What does hex division return?
For division the calculator shows the integer quotient and the remainder, mirroring how integer division works. Division by zero is blocked with an error message.
Which characters are valid hex input?
Only the digits 0–9 and letters A–F (case-insensitive) are accepted. Any other character, including the 0x prefix, triggers a validation error.
Why convert hex to binary and decimal?
Seeing all three bases side by side helps when debugging low-level code, working with memory addresses, or learning how number systems relate to one another.
