Decimal Precision

Hello,
I'm trying to design and test a three-level inverter. The switching interval used by Space Vector Modulation (SVM) is very narrow, that is, the time slot are of extremely quick duration. Is there a way to increase the decimal precision of matlab/simulink? My model is using a continuous solver with a fixed step time of 1e-6. The output of my basic S-function is rounding up to 4 decimal places. For example t = 0.2505 rather than t = 0.25045. Obviously there will be a limit to the precision achieved by the application. Is 4 decimal places the limit? Any help would be greatly appreciated.

You are merely seeing the DISPLAY precision, not the actual double precision value stored in matlab. Instead, try this:
format long g
