represented by the target type, then <code>None</code> is returned.</p>
<p>A value can be represented by the target type when it lies within
the range of scalars supported by the target type.
For example, a negative integer cannot be represented by an unsigned
integer type, and an <code>i64</code> with a very high magnitude might not be
convertible to an <code>i32</code>.
On the other hand, conversions with possible precision loss or truncation
are admitted, like an <code>f32</code> with a decimal part to an integer type, or
even a large <code>f64</code> saturating to <code>f32</code> infinity.</p>
