EMTH-CHSIN: Changing the Sign of a Floating Point Number Parameter Description Floating Point Value (Top Node) Floating Point Value with changed sign (Middle Node) The first of two contiguous 4x registers is entered in the top node. The second register is implied. Register Content Displayed First implied The FP value whose sign will be changed is stored here. The first of four contiguous 4x registers is entered in the middle node. The remaining three registers are implied Register Content Displayed First implied Registers are not used but their allocation in state RAM is required. Second implied Third implied The top node FP value with changed sign is posted here. Note: To preserve registers, you can make the 4x reference numbers assigned to the displayed register and the first implied register in the middle node equal to the register references in the top node, since the first two middle-node registers are not used. 840 USE 506 00 October 2002 169
