Sourceforge PIC float

[wannaBinventor]

I'm going to need to do some floating point math for a project where I'd like to convert Lat/Long data from a GPS to Universal Tranverse Mercator, and then to Military Grid Reference System. I've avoided floating point in the past by inflating them by orders of ten, but with this some of the math already has stuff in the millions and very small decimals, so inflating would lead to ridiculous inflation.

I've downloaded the sourceforge PICfloat collection of files. I must admit, it is information overload. Is there a tutorial file somewhere for this that explains things like "if you want to do trig, include these headers..." or "here is how you set up your files for a floating point division and here is what you need to call in order to bring it back to ascii numbers"

Thanks

Are you trying to do this in assembler?

 

[wannaBinventor]

Yes. That's all I know.

You might want a high level language for that sort of stuff. Swordfish BASIC would be my choice as it has a math module and is easy to learn and use.

I took a look at the language reference guide for Swordfish basic. It does look very easy to learn, but that 200 byte RAM limit will be tough to work with. If the full version was 50 or 60 bucks, I'd be all over it..... but $160+ is a little steep for me.

Careful programming practices make the 256 byte RAM barrier quite useful since there is no ROM limit. Constants use zero RAM.

Alright Blueroom, you guys have got me sold on Swordfish. Are there any tutorials out there that show you how to use it with the assumption that you don't know any BASIC? I googled and did not find much.

EDIT: How close is this to other basic languages? As in.... if to just google "basic language tutorial" would the info therein put me in the right direction?

It's more like VB It's not that hard to use just get to know the help file and you'll be good to go.

Have a look at this page https://www.sfcompiler.co.uk/wiki/pmwiki.php?n=SwordfishUser.NMEA

The built in help is great as it usually gives examples. Also here's a user module section, BASIC is very user readable.

Also look for gramo posts here.
