please see

The following floating-point exceptions are signalling

Dear Li, the IEEE_UNDERFLOW_FLAG and IEEE_DENORMAL messages are normal, and can be ignored. The meaning of the message is explained on Wikipedia: In a normal floating-point value, there are no leading zeros in the significand; rather, leading zeros are removed by adjusting the exponent (for example, the number 0.0123 would be written as 1.23 × 10−2). Denormal numbers are numbers where this representation would result in an exponent that is below the smallest representable exponent (the expon…
