 Degrees to radians. More...
 
constexpr float mrpt::DEG2RAD (const float x)
 Degrees to radians. More...
 
constexpr double mrpt::DEG2RAD (const int x)
 Degrees to radians. More...
 
constexpr double mrpt::RAD2DEG (const double x)
 Radians to degrees. More...

constexpr long double mrpt::RAD2DEG (const long double x)
 Radians to degrees. More...
 
constexpr double mrpt::operator"" _deg (long double v)
 degrees to radian literal operator (e.g. More...
 
template<typename T >
int mrpt::sign (T x)
 Returns the sign of X as "1" or "-1". More...
 
template<typename T >
int mrpt::signWithZero (T x)
 Returns the sign of X as "0", "1" or "-1". More...
 
template<typename T >
mrpt::lowestPositive (const T a, const T b)
 Returns the smallest positive number among a and b. More...
 
template<typename T >
mrpt::abs_diff (const T a, const T b)
 Efficient and portable evaluation of the absolute difference of two unsigned integer values (but will also work for signed and floating point types) More...
 
template<typename T >
const T mrpt::min3 (const T &A, const T &B, const T &C)
 
template<typename T >
const T mrpt::max3 (const T &A, const T &B, const T &C)
 
template<typename T >
int mrpt::fix (T x)
 Rounds toward zero. More...
 
template<typename T , typename K >
void mrpt::keep_min (T &var, const K test_val)
 If the second argument is below the first one, set the first argument to this lower value. More...
 
template<typename T , typename K >
void mrpt::keep_max (T &var, const K test_val)
 If the second argument is above the first one, set the first argument to this higher value. More...
 
template<typename T >
void mrpt::saturate (T &var, const T sat_min, const T sat_max)
 Saturate the value of var (the variable gets modified) so it does not get out of [min,max]. More...
 
template<typename T >
mrpt::saturate_val (const T &value, const T sat_min, const T sat_max)
 Like saturate() but it returns the value instead of modifying the variable. More...
 
template<class T >
mrpt::round2up (T val)
 Round up to the nearest power of two of a given number. More...
