title: Why am I getting an error converting a ‘float**’ to ‘const float**’?
body: <p>I have a function that receives <code>float**</code> as an argument, and I tried to change it to take <code>const float**</code>.</p>
  
  <p>The compiler (<code>g++</code>) didn't like it and issued :</p>
  
  <p><code>invalid conversion from ‘float**’ to ‘const float**’</code></p>
  
  <p>this makes no sense to me, I know (and verified) that I can pass <code>char*</code> to a function that takes <code>const char*</code>, so why not with <code>const float**</code>?</p>
