Abstract: An operating method of a floating point operation circuit includes, in response to receiving a first instruction, generating a first output by performing a fused multiplication and addition operation on a first input, a second input, and a third input. The method further includes, in response to receiving a second instruction, generating a second output by inverting one input of a fourth input, a fifth input, and a sixth input. Generating the second output includes generating a transform factor and a simplified value from the one input.
