What does Error 74: Floating underflow mean in Fortran?
A floating-point calculation produced a value smaller in magnitude than the smallest number the type can represent, typically rounded to zero.
A floating-point calculation produced a value smaller in magnitude than the smallest number the type can represent, typically rounded to zero.
Usually not harmful on its own if a near-zero result is acceptable; if the underflow is masking a real problem, check for a division by an unexpectedly large value earlier in the calculation.
