Returns the next lowest integer value by rounding down

<parameter>value</parameter> if necessary.
|

|
|
The return value of <function>floor</function> is still of type
|
||
|
|
<type>float</type> because the value range of <type>float</type> is
|
||
|
|
usually bigger than that of <type>int</type>.
