Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers 
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

James Bielman 5631f865b2 Update floating point calculations to use floats instead of doubles. 
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.

Andrew Tridgell dd200cba31 Math: added location functions to math library 
these do common calculations on struct Location
 2012-07-04 12:42:46 +10:00
Andrew Tridgell c30b0d85a3 Math: moved more template functions to the .cpp files 
save a bit more code space for larger functions
 2012-06-27 16:01:49 +10:00
Andrew Tridgell 289c64c0b9 Math: added vector3.rotate() and matrix3.rotation() methods 
these operate on a "enum Rotation" which defines a set of standard
rotations. These are much faster than our previous method, plus use
less memory

Andrew Tridgell f5e6dc0757 Math: added is_inf() on vector3f 2012-03-10 10:34:30 +11:00

Andrew Tridgell 62e92f406e AP_Math: make out vector and matrix elements used types with fixed sizes 
this prevents differences between CPU types
 2011-12-16 20:09:11 +11:00
jasonshort 7521ceed61 Vector3<T>() { x = y = x = 0; } 
changed to :
	Vector3<T>() { x = y = z = 0; }

DrZiplok@gmail.com 75e78dabae Back out the memset optimisation. It helps with code size but causes inexplicable link-time failures (undefined references to __cxa_pure_virtual). 
Thank you very much Mr GCC.  Can I have my evening back?

DrZiplok@gmail.com 290635b354 Minor code size optimisation; use memset to zero *this rather than explicitly assigning zero to the vector elements. Still not quite optimal for matrix3 as it gets three memsets, but still cheaper in terms of code size.

rmackay9@yahoo.com e930dacb4d AP_Math - initialise vector2 and vector3 x,y,z values to zero. Doug found (and I confirmed) that if vectors or matrices were declared in a function (i.e. a local variable), they would often have non-zero values. Global declarations don't have this problem - it's a C++ performance thing it seems.

DrZiplok@gmail.com 7721e622aa Rather than subclassing from the templated classes, just typedef directly to them. 
This should solve the issues related to assigning to the convenience types.

DrZiplok@gmail.com ac2e14c4ec Remove a bunch of probably wrong const cruft. Ditch the dubious array index operators from vector2.

DrZiplok@gmail.com 815e5f871a Remove the trivial operator= implementations, the default shallow copy is fine.

DrZiplok@gmail.com 646045ef44 Some minor fixes prompted while looking at the code for other reasons. 
Return non-const values from assignment.  Fix operator* for matrix3.
