Lucas De Marchi 69a9cd3625 AP_Math: add tests to is_equal() 
Contemplate the use of double values.
 2017-01-27 12:15:19 -08:00
Lucas De Marchi 4f8d2059f8 AP_Math: use right epsilon for is_equal() 
We are calling fabsf(), which returns a float. We should use the epsilon
from float type, not from the argument type passed to fabsf().

On the other hand when the double version is instantiated we do want to
use the std::numeric_limits<double>::epsilon() value.

This adds a branch to the function, but it's removed when the function
is intantiated by the compiler since the type is known at compile-time.

Fixes this warning when building for PX4:
../../libraries/AP_Math/AP_Math.cpp: In instantiation of 'typename std::enable_if<std::is_floating_point<typename std::common_type<_Tp, _Up>::type>::value, bool>::type is_equal(Arithmetic1, Arithmetic2) [with Arithmetic1 = double; Arithmetic2 = double; typename std::enable_if<std::is_floating_point<typename std::common_type<_Tp, _Up>::type>::value, bool>::type = bool]':

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.

Lucas De Marchi ae53920e5b build: don't build examples with old build system 
We currently check examples are buildable with waf which doesn't need
the libraries to be specified in a make.inc file.  Having the makefiles
there is misleading since people try to build and realize the build is
broken.

Gustavo Jose de Sousa 43d9e00ab7 AP_Math: AP_GeodesicGrid: use uint8_t for _neighbor_umbrellas

Gustavo Jose de Sousa 54889e4175 AP_Math: AP_GeodesicGrid: reduce number of inverses by half 
We don't actually need all of them, since the second half is for the opposite
triangles. In that case we just need to negate the resulting vector when
changing basis.

Gustavo Jose de Sousa f31161ecb6 AP_Math: AP_GeodesicGrid: remove triangles 
There's no need to keep those triangles, since we just need the inverses.
