Improper fractions can be written just the same i.e. 55/7 using the double-tap trick on the division symbol. Mixed fractions would be written as 3+3/4. You can also tap the Tip area (where the fraction results show) and change the fraction settings to show results as an improper fraction instead of the default representation.
Can you elaborate on this a bit more? You can double-tap the division symbol to represent a fraction number like 1/2 or 1/25 ... CALC will also automatically convert decimals to fractions in the upper left corner of the results area ... can you please provide specifics on your particular needs? Thanks
Thanks, we wish this were possible and you are not the first one to ask :-) Unfortunately, until Apple allows this, we are all stuck with the notification center widget for the time being...
Financial functions will be in the shared space soon! Please provide your insight what functions you’d like to see – you can get the first sample via this KB article: https://qapps.uservoice.com/knowledgebase/articles/933846-financial-custom-functions
BTW - You can create your own functions just look up the Custom Advanced Functions article in the Knowledge Base :-)
