What happens with that code:

----------------
$i = 1;
$a = myFunc( $i );

declare(strict_typehints=TRUE);

function myFunc( float $f )
{
     return otherFunc( $f );
}

function otherFunc( float $f )
{
     ...
}
----------------

As author of strict code I need to replace

     return otherFunc( $f );

by

     return otherFunc( (float) $f );


I'm not sure

- if this is what a strict coder wants and

- if you find an acceptable way to test your strict code if it works 
with non-strict code.
