Allow to perform bit operations on integer values
| GLM_FUNC_DECL vec<L, int, Q> glm::iround | ( | vec< L, T, Q > const & | x | ) |
Returns a value equal to the nearest integer to x.
The fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is fastest.
| x | The values of the argument must be greater or equal to zero. |
| T | floating point scalar types. |
| GLM_FUNC_DECL genIUType glm::log2 | ( | genIUType | x | ) |
Returns the log2 of x for integer values.
Usefull to compute mipmap count from the texture size.
| GLM_FUNC_DECL vec<L, uint, Q> glm::uround | ( | vec< L, T, Q > const & | x | ) |
Returns a value equal to the nearest integer to x.
The fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is fastest.
| x | The values of the argument must be greater or equal to zero. |
| T | floating point scalar types. |
