Hi. I am developing plugins for Caligari Truespace software. The plugins are
DLL's and use MFC. Primitive Itch developed a Delphi wrapper, and I helped
provide translations from the vc++ header files. The wrapper contains exports
from the tsxapi.dll which the Truespace application uses for plugins. Using
this wrapper, I can create DLL's for the extension of the Truespace
application. The problem I am having is with the floating point values in the
type float. They are making it hard to do checks. An example, I get a value
from a dll function that supposed to return 4.47 for a specific setting in the
application. Well when I read this value, it reads like 4.46999999999997 and I
get many similar problems like this. I have tried doing variable:=
StrToFloat(Format('%.2f', [variable])); however it returns the same value. What
can I do about this? I need to check for 4.47 yet its always returning false
because of the inaccuracy. Thanks,
Richard R. "Remnar"
