#144317 - Choosing an appropriate order of magnitude Responding to: ???'s previous message |

1,23 + 0.17 seems like a natural app for a standard slow and tedious 'standard' FP operation, but what is wrong with just doing 123+17 and inserting a decimal point onb the display, the user will not know the differennce. Probably the most obvious example to illustrate this is the cash register: If the numbers are $1.23 and $0.17 you could easily just do integer arithmetic in cents and, as you say, just move the decimal point on the display to have the answer back in dollars! In fact, some cash registers do have the decimal point just printed on the casing and it's not even in the display at all! and the same principle can be applied to other measures; eg, http://www.8052.com/forum/read.phtml?id=108347 http://www.8052.com/forum/read.phtml?id=143938 http://www.8052.com/forum/read.phtml?id=92089 |
