format number display in a IGUIStatic label

[humorstar]

I am trying to display a float number in a static label.
If I use the following code, I got a long display of the float number. How can I format it, for example, like %.3f in the C/C++ format string, so that it shows only three digits after the point?

Code: Select all

        text_centripetal[0]->setText(core::stringw(centripetal[0]).c_str());

Thank you,

Use the C format string

Code: Select all

c8 temp[20];
sprintf(temp, "%.3f", centripetal[0]);
text_centripetal[0]->setText(core::stringw(temp).c_str());

OK, that works. Thank you!
