[Bf-committers] OpenCollada issues (was Re: Meeting minutes, feb 14, 2010)

[Arystan Dyussenov]

This is only a hack though. For a real fix I don't have enough power and
knowledge at the moment.

The implication of this hack is that exported files will become larger than
normal. I think line "sprintf(buffer, doublePrecision ? "%.16f" : "%.7f", d);"
can be changed to "sprintf(buffer, "%.7f", d);" (because 16 digits in
fractional part is too much?)
