Rounding Floats

cekoivisto

In my java program I would like for the compiler to not automatically round my float values. I believe by default it rounds to 6 decimal places. Since I am using quite a complex formula involving sin and cos functions I would like to keep quite a few decimal places. How do I prevent it from automatically rounding. Maybe like: float x=3.123443234 float y=frozenFloat(x + 0.00000001) //x==3.123443244

Use double type: https://Processing.org/reference/double.html
And suffix all your fractional literals w/ d:

double x = 3.123443234d;
double h = 1e-3d;

For math functions, prefix all of them w/ Math.:
http://docs.Oracle.com/javase/8/docs/api/java/lang/Math.html

double n = Math.sin(x) + Math.sqrt(h);

This helps me a lot! Thanks
