| typedef boost::detail::thread::singleton< class Random_ > sr_math_utils::Random |
This is the usable singleton of the Random class.
The typical usage for this class is: -> generate double betwen 0 and 1 sr_math_utils::Random::instance().generate<double>()
-> generate integer between 0 and 10 sr_math_utils::Random::instance().generate<int>(0, 10)
-> generate double betwen 0 and 10 sr_math_utils::Random::instance().generate<double>(0, 10)

| static uint64_t sr_math_utils::counter_with_overflow | ( | uint64_t | full_value, | |
| uint16_t | new_value | |||
| ) | [inline, static] |
Increment a counter given a value which can overflow.
WARNING: only works if called often enough: if new_value > last_value but overflowed between the 2 calls, then we're not able to detect the overflow.
| full_value | the full value (with no overflow) | |
| new_value | the new value we received from the motor. |

| ) | [inline, static] |
Interpolate linearly between the 2 points, for the given value
y = y0 + (x-x0)*((y1-y0)/(x1-x0))
| x | the X value to compute the interpolation for. | |
| x0 | the X value of our first point | |
| y0 | the Y value of our first point | |
| x1 | the X value of our second point | |
| y1 | the Y value of our second point |

| static int sr_math_utils::sign | ( | double | x | ) | [inline, static] |
Checks the sign of a given number.
| x | the number we want to study. |

| static double sr_math_utils::to_degrees | ( | double | rad | ) | [inline, static] |
