The point is "usage of FP Math routines in C64 ROM for 16 bit values". The question title is obviously there. JeremyP provided usage with an example, that is what I needed. | |
| Oct 26, 2018 at 9:07 | comment | added | wizzwizz4♦ | @Digerkam Then why didn't you ask "what's the fastest way of multiplying two 16-bit integers in C64 assembly?" We're not psychic! :-) I recommend reading How to Ask before asking questions in future, so you don't have this whole big problem again. | |
| Oct 25, 2018 at 18:24 | comment | added | Digerkam | @Jules You are right, but using FP is very small part of my project, and I stuck in using FP side. Intention of asking the question was not facing more issue than FP usage. I am a software engineer and as you understand I am very bored to recieve life lessons than a few line of code... I am aware of that it is very a few line, but you know, I was looking for someone who experimented FP math and give an faster solution than me. That was the purpose of the question. | |
| Oct 25, 2018 at 16:47 | comment | added | Jules | @Digerkam - the answer here is quite clear even to a non expert. I've never programmed on the C64 (other than simple BASIC stuff), and my experience of 6502 assembly in general is fairly limited (a couple of small projects on the BBC micro), but I'm sure I could turn this into working code within an hour. In general, understanding how something works is more useful than having code to copy and paste because c&p code almost always needs customizing for the application, and if you don't understand it you can't do that. It's hard with most languages but essentially impossible in assembly language | |
| Oct 25, 2018 at 14:56 | comment | added | Digerkam | You are partialy right: yes if it is an huge code action, or touching any know-how, then I must hire someone. no if it is an simple code problem, or asking voluntary expert help. in SE sites which focusing coding, answers are full of codes, and knowledges which coming from experts without any payment. SE very popular thanks to this volunteer people. or it would be nothing. But you guys quite right about: this is not a forum site. But "Please watch your tone" is not an good calling, and never open nice doors. In the morning it was not this on my mind about FP in C64. Thank you. Regards. | |
| Oct 25, 2018 at 14:29 | comment | added | wizzwizz4♦ | @Digerkam Your response suggests that you are after somebody to write code for you. Generally this is something people are paid to do; might I suggest hiring a programmer? | |

@Raffzahn There's not a way to make linked footnotes, unfortunately; Stack Exchange ignores ID links like [this one](#anchor) ([this one](#anchor)).

| Oct 25, 2018 at 12:59 | comment | added | wizzwizz4♦ |
For references, I often use <sup>[\[1\]][1]</sup>. That gets old really fast, though; it'd be good if there was built-in support for footnotes and references.

You know, you can get much better-looking footnotes by using the sup tag, such as <sup>(1)</sup>.
