Yeah.  I would expect some differences.  The Double (DBL) has twice as many bits to represent an number than a Single (SGL).

SGL only gives you about 7 decimal digits of precision and you are doing quite a few operations, accumulating more rounding errors. The DBL result is significantly more accurate. SGL has the advantage of smaller data structures. You need to decide if it is precise enough. For example if the result drives a 16bit analog output, the difference is irrelevant.
