# Hexadecimal, octal, binary, oh my! [duplicate]

This is a code golf puzzle: shortest byte count wins. The program should do the following (standard loopholes obviously forbidden):

2. Convert to octal
3. Then interpret the digits as if in decimal (765 octal -> 765 decimal)
4. Divide the number by two

## Example:

Input: 4a3d Output: 5809.8

4a3d -> 45075 -> 45075 -> 22537.5 -> 5809.8

• Welcome to PPCG! I'm not the downvoter, but personally I'd vote this as a duplicate of base-conversion challenge, since that's the same, just repeated. I'd suggest you to use our sandbox next time, it can help detect potential problems in the challenge. Apr 14, 2018 at 14:44
• Hello, welcome to the site. I downvoted this challenge because it is a series of tasks, with no real motivation. I don't think the challenge is interesting. That being said don't feel discouraged to keep writing questions. Just because I think this challenge is bad doesn't mean I think you won't write good challenges in the future. Apr 14, 2018 at 15:03
• The most recent challenge I have upvoted was this. The main criteria I look for in a question are 1) Whether the challenge offers something new I haven't seen before 2) Whether the challenge is cohesive, that is whether its internal parts make sense with one another. 3) an arbitrary do I think it is fun criterion. If you want to get good at writing challenges I would suggest reading this. You might also look at this. Apr 14, 2018 at 15:14
• @SriotchilismO'Zaic It's been about a year since I created this question. Thanks for the feedback you gave, as it really helped me in future questions to avoid this mistake! May 3, 2019 at 23:38

p=parseInt,a=>(p(p(a,16)[s='toString'](8))/2)[s](16)


toString on an integer converts the integer to a string in that base.

• Had no idea the .toString(base) thing existed. Upvote for teaching me something new! Apr 14, 2018 at 14:45
