Simulator, 0.02 time delays and weird age of tokens

[Jiri Srba]

Consider the example net attached and in the simulator do the following:

0.5
T0
T1
0.02
T0
0.001
T1

and now check the age of tokens in place P0, it is 0.520999997

Probably some rounding error but this should not really happen after the time delays
that do not even reach the precision of the reals ...

[Jiri Srba (srba)]

This should be fixed.

[Kenneth Yrke Jørgensen (yrke)]

The problem is not realy the precision of the float, but the accuracy

   * Precision - how fine a distinction can be made between two close values.
   * Accuracy - how close the value is to the correct value.

We have fixed this problem by using java.text.DecimalFormat
