If everything is implemented as it should, you should provide the functions: isnan(), finite(), isinf() isnan() should return 1 (true) when its parameter is not a number isinf() should return -1 when its parameter is a negative infinite value, +1 when its parameter is a positive infinite value and 0 otherwise. finite() should return 1 when both isnan() and isinf() return 0 If these functions are already available, use them. If they're not, you have to create them yourself. Next thing to do is generate apropriate values that will never occur otherwise. If these conditions are met, it should be rather simple to port RRDtool (with respect to the numbers anyway). Note that RRDtool *should* be OK but maybe you find something wrong. When you do, please let us know.
