WebUnderflow. On a Win32 platform, FTN95 allows you to detect floating point underflow by either a) calling PERMIT_UNDERFLOW@ (.FALSE.) or b) using /UNDERFLOW on the command line (in which case the call to PERMIT_UNDERFLOW@ is planted for you. If you do not permit underflow, an exception is raised at runtime when an underflow occurs. WebI recall the lecturer saying "Floating point numbers are approximations. Use integer types for money. Use FORTRAN or other language with BCD numbers for accurate computation." ( and then he pointed out the approximation, using that classic example of 0.2 impossible to represent accurately in binary floating point).
