| Nov 10, 2014 at 13:21 | comment | added | Murta | @ChrisDegnen I'm using N@Round[100*4.811,1/100] to solve that. But take care with automatic Map compilation, details here: 65298 | |
| Nov 9, 2014 at 23:19 | comment | added | Chris Degnen | Nice observation. That also occurs with 481/100. but not with N[481/100] so the safer usage is to round to integer like N[Round[100*4.811]/100] | |
| Nov 9, 2014 at 22:56 | comment | added | Murta | There are some problems with Round. For example, try Round[4.811] and you get 4.8100000000000005, not 4.81 as expected. | |
