Center node: "building financial accuracy into spreadsheets"
  Abstract: Students learning how to apply spreadsheets to accounting problems are not always well served by the built-in financial functions. Problems can arise because of differences between UK and US practice, through anomalies in the functions themselves, and because the promptings of Wizards' engender an attitude of filling in the blanks on the screen, and hoping for the best. Some examples of these problems are described, and suggestions are presented for ways of improving the situation. Principally, it is suggested that spreadsheet prompts and 'Help' screens should offer integrated guidance, covering some aspects of financial practice, as well as matters of spreadsheet technique.

Connected through hyperedge HE-1 (induced by source paper "bientropy the approximate entropy of a finite binary string"):
  with members:
    - "user defined spreadsheet functions in excel"
    - "spreadsheets and the financial collapse"
    - "the importance and criticality of spreadsheets in the city of london"
