title: Why does my CAST to a float give an "invalid number" error in Oracle?
body: <p>I have the following example:</p>
  <pre><code>create table test_1(c1 float);
  insert into test_1 values(cast('000000000000001425.6' as float));
  </code></pre>
  <p>When I want to insert the value, I have</p>
  <blockquote>
  <p>ORA-01722: invalid number</p>
  </blockquote>
  <p>How can I pass over this error, please?</p>
