Convert numbers to other bases

You can use the bin, oct, dec and hex functions to convert numbers to binary, octal, decimal and hexadecimal bases, respectively. You can call those using hex(2^16 - 1), or 2^16 - 1 // hex, but they are also available as targets of the conversion operator ->/to, so you can write expressions like:

Examples:

0xffee to bin
42 ot oct
2^16 - 1 to hex

You can also use base(b) to convert a number to base b:

0xffee to base(2)
