[Qgis-developer] Strange modulus calculations in QGIS

[Andreas Neumann]

Hi,

I am using modules calculations to distinguish major from minor contour 
lines. However, the modulus calculations have two issue:

1. the results have rounding issue:
f.e. 467.9 % 0.2 results in 0.0999999999999513 - I know I could use a 
round function as a workaround - but it is annoying!

2. there are very strange results:
468.0 % 0.2 results in 0.1999999999999974 -> I would expect a result of 
"0"

Is there something we can do to fix these two issues?

Thanks,
Andreas
