GLM_FUNC_DECL genIUType

log2 (genIUType x)

Returns the log2 of x for integer values. Usefull to compute mipmap count from the texture size.

GLM_GTC_integer
GLM_FUNC_DECL vec< L, int, Q >

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.
