I'm using Processing 0157 for Linux, Intel X86, and I have NOT linked to
another Java. The problem I see is with the following code:

float digits = 1132.0 * 0.0001;
text("Digits: " + digits, 50, 50);

Which displays :

Digits: 0.113199994

which is incorrect, but when I invert 0.0001 and divide by 10000 instead I
get the following :

1132.0 / 10000 = 0.1132

which is correct. They are both technically the same operation and should
have the same results. I tested other values from 1119.0 through 1132.0
with some values returning incorrect results and others returning the
correct results. I also tried :

1132 * 0.8356 = 945.89923 which should have been :

945.8992

floats are 32 bit floating point numbers. they are not perfect, they are
approximations. they offer around 4 to 6 digits of accuracy depending on
the case in which they're used, so you're going to get poor results if you
multiply a smallish number by 0.0001.

use a double if you need better numerical accuracy, then convert to float
before drawing since none of the APIs use doubles.

Actually, I thought about that too. But after testing larger/smaller
sequential numbers and getting the correct results I came to the conclusion
that there was something amiss. I don't know that it's even in Processing,
maybe it's in Java. I just thought I'd post it in case there's a real
problem. The fact that I can get the correct results by inverting and
multiplying is more than sufficient for my needs.
