GLM_FUNC_DECL vec< L, uint, Q > | uround (vec< L, T, Q > const &x) |
Include <glm/gtc/integer.hpp> to use the features of this extension.
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.
Can be reliably using 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. |
