making i=0.<BR>> <BR>> If you're using .NET you can use the
Math::Round method:<BR>><BR>> float j =
0.8983f;<BR>> int i =
(int)Math::Round(j);<BR>><BR>> making i=1.<BR>> <BR>> Hope
this helps!<BR>> <<A

*Subject:* [vtkusers] Float to Int<BR>><BR>> Hi
all, i'm having a bit of difficulty converting my
texture<BR>> coordinates (as a float from 0 ->
1) to a coordinate (as an<BR>> integer from 0 -
> size of image) My current method simply
floors<BR>> the float, i.e. 0.8983 would be a 0,
however this isn't very<BR>> accurate as it should
be a 1.<BR>> <BR>>
Can anybody help me please?<BR>>
<BR>> Also if there is a better way of doing this
rather than rounding,<BR>> i would appreciate any
comments.<BR>>
<BR>> Thank you for your
time.<BR>><BR><BR></BLOCKQUOTE></BODY></HTML>
