(...) 256 * 128 = 32768, one higher as the biggest positive integer value. The cast to long would help, but your cast is too late. I have not tested, but I think rc += ( (long)b->magnitude * (long)TA_costable[...] ) >> 7; will help. Try output in (...) (23 years ago, 30-Jan-02, to lugnet.robotics.rcx.legos)

<snipped code> (...) Robert, this is a classic problem with ranges of singed numbers in C rx = (long)(a->magnitude * TA_costable[a->direction]) >> 7; I don't have an RCX in frot of me, but I think you need to cast a->magnitude to long before the (...)

This problem, unlike the other, is definitely not a result of my eyes/brain being tired or something. I thoroughly displayed every value before and after evaluation and the result is ***WRONG***. Here is the code and the values: typedef struct { int (...) (23 years ago, 30-Jan-02, to lugnet.robotics.rcx.legos)
