What does forrtl 300 — Floating Underflow Traps Reported mean in Fortran?
Reports, at program exit, how many times a floating-point underflow — a result too small to represent as a normal number — was trapped during the run. Often benign, but a large count can indicate values are being driven toward zero somewhere they shouldn't be.
Reports, at program exit, how many times a floating-point underflow — a result too small to represent as a normal number — was trapped during the run. Often benign, but a large count can indicate values are being driven toward zero somewhere they shouldn't be.
Usually safe to leave alone in production; if debugging unexpected precision loss, rebuild with traceback to identify which statements are producing the underflows and confirm they're expected.
