Using floats in div programs


Hi, I have this floating point DLL that could be useful to someone. Maybe I think DomCook might be interested to experiment a bit. It needs some adjustments and has few functions implemented, but it could be improved and expanded. Then I could make some example of use.

Impressive.
I'm looking forward to seeing some more examples.

By the way it's just Dom really or Dominic if you like typing.
I haven't got around to figuring out if I can change my user name. I quite like the idea of calling myself "Tumbleweed".

Hahaha, for a while i was called "Dr Kleiner" and other pseudonyms ... but I became known as Vortigano playing MOBA games, so I preferred to leave it so that someone who looks for me can find me. In the end, the name takes its value according to our achievements and good deeds.
I fixed the youtube link because a server problem. :thumbup:

dom cook I've sent a u2u msg.
I wanted to tell you about the functions that the dll had:
addfloat(in_a, in_b, out_c);
subfloat(in_a, in_b, out_c);
divfloat(in_a, in_b, out_c);
mulfloat(in_a, in_b, out_c);
float_to_int, sin_float, cos_float.
Then I stopped when I was writing a parser to put "4*10 ^ -5" and things like that... but if you find it useful, I would try to continue it.

Sorry for the untidiness, but here you have a quick example.
I forgot to mention the sha-256 of the DLL

I have a problem. I don't think DIV likes the import command. Does the .dll need to be in a specific folder?

A cictec update broke the dll system ... I used a previous compilation of the cictec update since I started writing dlls, and I think it was removed from the server. So I think I should upload the previous update of cictec.
This means that nobody could use any dll that I have built :/

This example uses cosine sine and float_to_int ().
Remember that the trigonometric calculations are in radians, they are not in degrees. ^u^)/

I'm working on the parser in c... is going to ruin my brain, but I love it.
When I learn to analyze variables in a string and fix some bugs I will mix it with the divdx dll.

Blank line to exit, accept "+ - / * ^".
Exponents only positive integers for now.

Vortigano I think we should discuss this. There is no reason why we could not include this in the main DIV core. That is how mode8 started (as a DLL), and how the original div2 netplay began - there are even hints of this in the original source still today!

Is the dll source available? Could you share it with me privately if you don't want to publically share it so we can consider if DIV could benefit from it being included in the main tree.

For now I'm not interested in making it public, but I can give you a copy of the source code when I adjust some things. Maybe you could improve the parser as I have very little experience with C (less than 1 year) and programming in general. I only have strong experience with microchip RISC assembler. I wish someone could first use it for something and then consider publishing the source code... that would make me happy.

I think what could be added would be inside the div-core a definition for float of 4bytes that I suppose would not break the alignment of the int32_t memory.
This way we could simply declare and define a DIV variable as "float var_x = 0.05;".
