Chapter 6 Applied Instructions API 1512 Symbol: S ： Source device Double word D ： Device in which the result is stored Double word Explanation: 1. The square root of the floating-point number in the register specified by S is calculated, and the result is stored in the register specified by D . 2. If the operation result stored in D is 0, SM600 is ON. Example 1: When X0.0 is ON, the square root of the floating-point number in (D1, D0) is calculated, and the result is stored in (D11, D10). Additional remark: 1. The value in the device specified by S only can be a positive value.
If the value in the device specified by S is a negative value, the operation error occurs, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2003. 6-341 Instruction code Operand Function FSQR P S, D Square root of the floating-point number Device X Y M S T C HC D L SM SR E PR K 16# “$” DF S D Pulse instruction 16-bit instruction (5-6 steps) 32-bit instruction AH500 AH500 -
