template<typename T > |
T | npl::clamp (T inf, T sup, T v) |
| Clamps value to range of [inf, sup]. Values outside will be pulled to either sup or inf, whichever is closer. More...

template<typename T > |
T | npl::wrap (T inf, T sup, T v) |
| Wraps and index based on the range [inf, sup] (when v is outside that) range. Thus inf = 1, sup = 5, v = 0 will wrap around to 4, and v = 6 would wrap around to 1. More...
