Comments on Convert to Hexadecimal

Post

Convert to Hexadecimal

+2
−1

Challenge

Write a program that takes in a number greater than or equal to 0 and outputs its representation in hexadecimal (base 16).

Examples

0     => 0
1     => 1
10    => A
15    => F
16    => 10
107   => 6B
153   => 99
207   => CF
1000  => 3E8
10381 => 288D
48821 => BEB5

Rules

  • No built-in hexadecimal functions.
    • More generally, any base conversion function is considered to be disallowed.
  • Letters can be uppercase or lowercase.
  • It should work at least for all inputs greater than 0 up to the language's default type limit.
  • Leading zeros in the output is fine. (i.e. 000003E8 for 32-bit numbers)
  • This is [code-golf], so shortest code wins.

Input in integer type? (4 comments)
What defines a "Hexadecimal function"? Is it strictly a `toHex` function? Is `.toString(16)` banned? ... (6 comments)

Can the input be in an integer type (e.g., C's int)? While those values are commonly displayed in base 10, they typically are actually stored in binary.

…isn’t that how integers are typically stored in computer memory? I don’t see what you’re trying to ask

Yes, it is, but your question text reads "takes in a number in base 10".

Sorry, I can change it to “a positive integer >= 0”
