glm::float_distance
GLM_FUNC_DECL vec< L, int64, Q > float_distance(vec< L, double, Q > const &x, vec< L, double, Q > const &y)
Return the distance in the number of ULP between 2 double-precision floating-point scalars.
glm::prev_float
GLM_FUNC_DECL vec< L, T, Q > prev_float(vec< L, T, Q > const &x, vec< L, int, Q > const &ULPs)
Return the value(s) ULP distance before the input value(s).
glm::next_float
GLM_FUNC_DECL vec< L, T, Q > next_float(vec< L, T, Q > const &x, vec< L, int, Q > const &ULPs)
Return the value(s) ULP distance after the input value(s).
glm::int64
detail::int64 int64
64 bit signed integer type.
