Float add error result

fakepuppet

I notice Processing error with float calculation.. My code float a=0.12+0.12+0.12; println(a); Why I got 0.359xx instead 0.36?

This discussion talks about this in some detail. The answers by blindfish are very clear.

Thanks @quark. I read this post https://support.microsoft.com/en-gb/kb/214118 then I use "nfc" function to correct the calculation (4 digit after comma)..

float a=0.12+0.12+0.12;
String aconv=nfc(a, 4);
String[] asplit=split(aconv, ",");
aconv=join(asplit, ".");
a=float(aconv);
println(a);
