glm::next_float
GLM_FUNC_DECL genType next_float(genType const &x)
Return the next ULP value(s) after the input value(s).

glm::uint
unsigned int uint
Unsigned integer type.
Definition: type_int.hpp:171

glm::float_distance
GLM_FUNC_DECL uint float_distance(T const &x, T const &y)
Return the distance in the number of ULP between 2 scalars.

glm::prev_float
GLM_FUNC_DECL genType prev_float(genType const &x)
Return the previous ULP value(s) before the input value(s).
