unexpected results summing double type values

[Lynn Miller]

I am stumped about something and I hope someone can help me. I have been
using Java for almost one year and can't figure this one out.

I am using Microsoft Visual J++ 6.0 with SP3 and the latest VM.

If the following code is run, the results will tell me that they do NOT equal:

double sumofDebits = 0;
double sumofCredits = 0;

sumofDebits += 5.54;
sumofDebits += 95.01;
sumofCredits += 100.55;

if (sumofDebits == sumofCredits)
Win32.MessageBox(0,"Equal","Title",0);
else
Win32.MessageBox(0,"Not Equal","Title",0);

However, if I change the values from 5.54 and 95.01 to 5.53 and 95.02, respectively,
it will say they equal (which it should)

Any ideas?

Thanks,

Lynn Miller
