→Underflow

An underflow is the condition where the result of a calculation is too small to be be represented. Compare: →Overflow
An underflow can occur when the result of a floating point operation is smaller in magnitude (that is closer to 0.0) than the smallest floating point number is. Examples for underflows: REAL values within the range from -1.4e-45 to 1.4e-45 (exception: 0.0)
