It's the problems that I have seen when they weren't modeled well that lead to me to write this post!Anonymoushttps://www.blogger.com/profile/06508106623614342269noreply@blogger.comtag:blogger.com,1999:blog-5330549408956705153.post-11285816887051164892012-10-29T04:07:16.895-07:002012-10-29T04:07:16.895-07:00Yes, it's good to remind people about the impo...Yes, it's good to remind people about the importance of units. I wrote an article on the subject some time ago, with particular reference to angles. I am sure you will find it interesting: http://britastro.org/computing/morsels_angle.html<br /><br />I firmly believe that measured values should live in objects, each of which contains the value, standard error and units. The units should be defined by a class (typically an enum) firmly associated with the class of the measurement itself, such as Angle.Units. The units have to be specified when constructing the object and the object can return the value converted to any specified units from the relevant Units class.Anonymoushttps://www.blogger.com/profile/11692001718786814278noreply@blogger.comtag:blogger.com,1999:blog-5330549408956705153.post-4659286032738550662012-10-28T11:17:57.937-07:002012-10-28T11:17:57.937-07:00Thanks, fixed it.

But I did get it right in the rest of the paragraph! ;-)Anonymoushttps://www.blogger.com/profile/06508106623614342269noreply@blogger.comtag:blogger.com,1999:blog-5330549408956705153.post-32582977841060229272012-10-28T10:55:19.344-07:002012-10-28T10:55:19.344-07:00Nice post!

Just a little comment, something I remember from my high-school teacher: she used to say "do not use 'sec' for seconds, use 's'"<br /><br />I searched on Google and found this:<br />http://physics.nist.gov/cuu/pdf/sp811.pdf<br /><br />Check out section 6.1.8!<br /><br />Ciao<br />CristoforoGiovannahttps://www.blogger.com/profile/04927762764838175084noreply@blogger.com
