You can send out all the derived binaries you want royalty free, but the sources have to stay within your organization. The routines are: FP24FLT - Convert 32 bit fixed point to floating. FP24ADD - Add. FP24SUB - Subtract. FP24MUL - Multiply. FP24DIV - Divide. FP24MIN - Find minimum of two values. FP24MAX - Find maximum of two values. FP24FIX - Convert floating point to 32 bit fixed point. The interface and operation of all routines are well documented in the source code comments. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
