The modulo operator as implemented in the Mathematical Expression patch casts
the numbers (normally doubles) to 32 bit signed integers. Because of that,
you'll not be able to use numbers larger than ~2,147,483,647 (2^31-1) for the
modulo operation.
Also note that you're adding small values (patch time) to gigantic values.
Floating point numbers don't handle that sort of thing particularly well in
general: often the smaller number simply disappears, or experiences odd
rounding/truncation.
For example:
[this is javascript]
> function (__number outputNumber) main (__number inputNumber[2])
> {
> var result = new Object();
> var i = 0;
> result.outputNumber = inputNumber[0];
> for(i=0;i<10000000;++i)
> result.outputNumber += + inputNumber[1];
> return result;
> }
if you set the inputs to 1e10 and 0.1 respectively, you'd expect to get
10001000000 (1e10 + 10000000 * 0.1), but you actually get
10001000003.8147....
that bottom cruft is due to floating point math being inexact. This example
exaggerates its effect by repeatedly adding (instead of multiplying and then
adding), but it's something one must absolutely be aware of when mixing very
large and very small numbers.
