hi,

working on a simulation patch i've difficulties with wrong results from additions.

in a periodic loop a [value V] is added up with a constant.

a simplified version:

[t b] - [v V] - [+ 0.0025] - [v V]

it starts at 0.

looking at the numbers when put in an array i see that e.g.

the value that should be 0.1250 is actually 0.1249999

and 0.75 is actually 0.7499994.

in the loop this variable is used for calculations which multiply the deviations.

why does this simple addition not giving the exact result?
