50% of the spreadsheets I use are for finance, and when I, for example, am apportioning a phone bill across projects, I need the apportionments after they are rounded up/down to add up to the total bill so I can post a balanced journal. As I work under pressure I don't want my flow of work interrupted by having to continually download update the schedule, save a temporary file on my laptop, the upload it back to the cloud storage then dleting the temporary file. The flapping around sometimes raking longer than the actual work. the sooner 100% comparability becomes international law, the better.
