Peter Barker 8df2d4998b AP_Math: improve gating of use of AP_InternalError library 
- gate calls into library directly on the define
 - INTERNAL_ERROR becomes empty if library not compiled in

Ryan Friedman cf2b65877e AP_Math: Move conversion utilites next to AP_Math 
* This is next to the constraining functions

Iampete1 702245f89e AP_Math: calc_lowpass_alpha_dt: remove unused constrain 2022-06-08 17:11:08 +10:00
Andrew Tridgell a95b429acc AP_Math: added unsigned versions of constrain functions 
sometimes it really does matter that we use constrain_uint32() instead
of constrain_int32(). For example, if we have a value like 0xFFFFFFFF
then the result will be very different

we should use unsigned constrain when dealing with unsigned values

Andrew Tridgell 66b4e92444 AP_Math: make fill_nanf() use a signalling NaN 
we want use of these values to trigger a FPE

Peter Barker 6fe09b6120 AP_Math: move is_valid_octal into adsb 
This doesn't ensure the value is octal digits - there's more magic in
it.

Peter Barker 975804fa35 AP_Math: remove unit_mod concept from wrap functions 
devcall decided it would be clearer to have non-shared implementation
for the _cd variants

Peter Barker 6af0dcfed0 AP_Math: create a constrain_int64 
The template system doesn't work across 32/64 bit builds (SITL
vs fmuv4), probably because int is typedef'd to int64

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()
