tState

Declaration

typedef float tState;

changed from int to single-precision floating point.
The decision to change this data type in API version 1.1 was not made lightly. Do not expect it to change again. I decided to do it early in the development of R2DToo before many models had been developed. The reason the change occured was because I found I needed the advantages of floating point numbers more frequently in my models than integers (the main advantage of which was bitwise manipulation). The speed penalty is estimated at 5% and was deemed worthwhile for the added convenience of rational numbers.
