Date: Sat, 1 May 2004 01:13:04 -0400 rb->sqrt() is not working. sqrt() is not defined in plugin API. It's no big deal, though. I'll just leave this function as x/2. My interface is a little complex than yours. I simulate the interface of the standard calculator in Windows 2k, which has backspace, memory, 1/x, sqrt, etc. And I draw some lines and grid, too. I decided to write display part myself. Actually, I've already finished this part. But then I decided to rewrite the whole core code and add support to scientific number format. I'll post my code as soon as it's in alpha version. >tinousus_at_yahoo.com wrote: >> The problem I met is that: I always get error of "undefined sqrt() funtion" even I include math.h when > > >Try rb->sqrt() >/me was the one that was developing the other calc plugin. > > >If you can find any way to typecast a double to a string without the use >of snprintf, let me know, because I have a very basic LCD working ( >http://kaboofa.liek.us/stuff/calcshot.png [sic] ) _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2004-05-01 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
