This calculator can handle input numbers in several different bases:
- Decimal (Base 10): Numbers that do not start with a zero like 15 or
3.14e15. Decimal numbers can contain digits 0-9, decimals, and scientific
notation.
- Hexadecimal (Base 16): Integers that start with a zero x like 0x1a5.
Hexadecimal numbers can contain digits 0-9 and a-f (or A-F) but no decimal or
scientific notation.
- Octal (Base 8): Integers that start with a zero like 073. Octal numbers
can contain digits 0-7 but no decimal or scientific notation.
- Binary (Base 2): Integers that start with a zero b like 0b101. Binary
numbers can contain digits 0 and 1 but no decimal or scientific notation.
^ is a bitwise xor operation. To raise a number to a power use pow()
function.
