The <type>string</type> will be evaluated as a <type>float</type> if it
contains any of the characters '.', 'e', or 'E'. Otherwise, it will be
evaluated as an <type>integer</type>.
If the <type>string</type> does not contain any of the characters '.', 'e',
or 'E' and implied numeric value fits into integer type limits (as defined by
<constant>PHP_INT_MAX</constant>), the <type>string</type> will be evaluated
as an <type>integer</type>. In all other cases it will be evaluated as a
<type>float</type>.
