Restituisce il primo intero più grande di
|
|
<parameter>numero</parameter>, se necessario.
|
|
Il valore restituito da <function>ceil</function> è ancora di tipo
|
|
<type>float</type>, poiché la gamma di valori del tipo <type>float</type> è
|
|
solitamente più grande di quella del tipo <type>integer</type>.
