Specifiche della virgola mobile in Simulink
Poiché i numeri a singola precisione utilizzano solo 32 bit, richiedono meno memoria dei numeri a doppia precisione, pur offrendo molti dei vantaggi dell'aritmetica in virgola mobile. Il tipo di dati a mezza precisione occupa solo 16 bit di memoria, ma la sua rappresentazione in virgola mobile consente di gestire intervalli dinamici più ampi rispetto ai tipi di dati interi o in virgola fissa della stessa grandezza.
