A data processing apparatus operate to process floating point operands is disclosed. The data processing apparatus comprises: an instruction decoder operable to decode an instruction for processing floating point operands; and a data processor operable to perform data processing operations controlled by the instruction decoder wherein: in response to the decoded instruction indicating operation according to a flush-to-zero semantic, the data processor is operable to process the floating point operands in accordance with the decoded instruction such that floating point operands having a denormal value are treated as zero operands; and in response to the decoded instruction indicating operation according to a denormal semantic, the data processor is operable to process the floating point operands in accordance with the decoded instruction such that floating point operands having a denormal value are treated as denormal operands.
