| 66 | //! | ||
| 67 | //! **Return value** | ||
| 68 | //! | ||
| 69 | //! 1. The call `is_flint(x)` is semantically equivalent to `is_flint (eve::frac(x))`; | ||
| 70 | //! This means that x represents an integral value. | ||
| 71 | //! 2. Always returns `true`. | ||
| 72 | //! 3. [The operation is performed conditionnaly](@ref conditional). | ||
| 73 | //! 4. The call `is_flint[pedantic](x)` also check that the input is not greater or equal to the | ||
| 74 | //! largest consecutive integer in the element type of `x` (`maxflint(as(x))`). | ||
