Lucas De Marchi 008ac0a2a8 AP_Math: remove unused double instantiation 2017-02-06 09:27:22 -08:00
Lucas De Marchi 87038d8ef1 AP_Math: add casts to consider literals as doubles 
Since we pass -fsingle-precision-constant to the compiler, add casts to
make literals real doubles.
 2017-02-06 09:27:22 -08:00
Lucas De Marchi 48d94db259 AP_Math: double constants need a type 
We can't use define since we use -fsingle-precision-constant and they
would be interpreted as float.

Lucas De Marchi 87c82ce0c6 AP_Math: add some more tests for constrain_value() 2017-01-27 12:15:20 -08:00
Lucas De Marchi 82d210144b AP_Math: remove warnings from constrain_value() 
Return type is T which can be an integral type, float or double. By
dividing by 2 we avoid float operation on the first case and do the
right thing on the second and third.

Lucas De Marchi 2605c7265b AP_Math: remove warnings from safe_asin() 
Return type is float, so operate on float types everywhere.
Fixes this warning while building for PX4:

Lucas De Marchi 69a9cd3625 AP_Math: add tests to is_equal() 
Contemplate the use of double values.

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.
