FEL

I många situationer blir talen för stora (överflöd) och fel uppstår. Indikeringen “E” visas på skärmen när detta inträffar. Innenhållet i minnet då felet inträffar kvarhålls dock. Om “0•E” visas då felet inträffar kommer “– – – – – – –” att skrivas ut i rött, och C CE måste användas för att tömma räknaren.

Fel kan uppstå i följande fall:

1.När svarets heltalsdel överstiger 12 siffror.

2.När minnet innehåller fler än 12 heltal. (Ex. M 999999999999 M+ 1 M+ )

3.När ett tal divideras med noll. (Ex. 5 0 )
