An sNaN is input in an operation, except copy, FABS, and FNEG, that generates a floating-point
value.
• When the EN.V bit in FPSCR is 0, the operation result (output) is a qNaN.
• When the EN.V bit in FPSCR is 1, an invalid operation exception will be generated. In this
If a qNaN is input in an operation that generates a floating-point value, and an sNaN has not been
input in that operation, the output will always be a qNaN irrespective of the setting of the EN.V bit
in FPSCR. An exception will not be generated in this case.
The qNAN values as operation results are as follows:
• Single-precision qNaN: H'7FBF FFFF
• Double-precision qNaN: H'7FF7 FFFF FFFF FFFF
See the individual instruction descriptions for details of floating-point operations when a non-
number (NaN) is input.
3.2.3
For a denormalized number floating-point value, the exponent field is expressed as 0, and the
fraction field as a non-zero value.
When the DN bit in FPSCR of the FPU is 1, a denormalized number (source operand or operation
result) is always flushed to 0 in a floating-point operation that generates a value (an operation
other than copy, FNEG, or FABS).
When the DN bit in FPSCR is 0, a denormalized number (source operand or operation result) is
processed as it is. See the individual instruction descriptions for details of floating-point
operations when a denormalized number is input.
