Name Label Operation
Error Flag ER ON if the source data is not recognized as floating-point
data.
ON if the source data is not a number (NaN).
OFF in all other cases.
Equals Flag = ON if both the exponent and mantissa of the result are 0.
OFF in all other cases.
Overflow Flag OF ON if the absolute value of the result is too large to be
expressed as a 32-bit floating-point value.
Underflow Flag UF ON if the absolute value of the result is too small to be
expressed as a 32-bit floating-point value.
Negative Flag N ON if the result is negative.
OFF in all other cases.
