GPS project question

When I look at the floating point libraries I seem to get completely lost and I find it difficult to follow. Do you suggest a website or any other source where I might be able to catch up to the curve.

Thanks for the quick reply

Nope, the only thing I can suggest is to 'relearn your math' (I'm not saying you can't add or anything, just rethink it)
Break what you think is complicated down to the simplest parts you can think of and build it back up...

Why using float anyways??? it's just slow and bloat your code for nothing.

Is this as this hard to figure out 12.34 is the same f thing than 1234 but with a point?

Just an idea from an old guy so far

When I try to shift everything I run into a overflow problem -- I have to square the solution to calculate the distance so the multiplication can only exceed #188. Is there any way to make a variable greater than word (16bits)? Or how would I make a new variable which takes over after 65k?

Thanks

Hi,

Have a look at the DIV32 Maths operator. This may help.
