[math] minimal step size exception has inverted numbers?

[Dennis Hendriks]

Hi all,

I use a minimum integration step size of 1e-15, and got this error message:
    org.apache.commons.math.exception.NumberIsTooSmallException: minimal 
step size (8.97E-16) reached, integration needs 1.00E-15

It was generated here in AdaptiveStepSizeIntegrator, at line 326:

              throw new 
NumberIsTooSmallException(LocalizedFormats.MINIMAL_STEPSIZE_REACHED_DURING_INTEGRATION,
                                                  minStep, 
FastMath.abs(h), true);

I would have expected:

    org.apache.commons.math.exception.NumberIsTooSmallException: minimal 
step size (1.00E-15) reached, integration needs 8.97E-16

That is, the numbers seem to be reversed...

Is this a bug, or am I missing something here?

Best regards,
Dennis
