Randy Mackay 37cfbc9ad5 AP_Math: float versions of wrap_360 and wrap_180 2014-02-15 05:27:45 +11:00
Randy Mackay a963ec7e3b AP_Math: bug fix to wrap_360 and wrap_180
angles above 720deg and below 3200deg might not have been properly
wrapped.
wrap_360_cd could return 36000 when really this should be wrapped back
to zero.

Andrew Tridgell 97b7130bb9 libraries: update license header to GPLv3
we switched to GPLv3 a long time ago, but neglected to update the
per-file license headers

Andrew Tridgell e2b0e07973 AP_Math: removed unused matrix rotation code
we only need to rotate vectors

Andrew Tridgell a295a01bbc AP_Math: added missing 90 degree rotations
this ensures we can handle all 90 degree rotations of the compass and
main board. A test in examples/rotations shows that we have them all.

Andrew Tridgell 2b1fcc964f AP_Math: added a quick test of floating point location accuracy
just confirming some maths ...

Andrew Tridgell 5434b2c017 AP_Math: update location code to avoid float rounding
this avoids manipulating global coordinates as float variables. Using
a float reduces our precision from 1cm to about 70cm.

This also adds location_diff() which will be used in the L1 controller
to avoid global positions in floats

Randy Mackay 7c9d9b9800 AP_Math: use DEG_TO_RAD in longitude_scale
Also increased accuracy of RadiansToCentiDegrees although it is like the
compiler will throw away the extra digits anyway.

James Bielman 4fa7bb1486 Add AVR compatibility header for missing math.h definitions.
- Define float versions of math functions to the double versions
  on AVR (eg. #define sinf sin).
- These macros appear to be missing in older versions of avr-libs.
- Include AP_Math.h rather than math.h to get these definitions.
