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). WebThe Fortran compiler supports several kinds of floating-point exceptions; a summary of their masked (or default) responses is given below: overflow:Overflow is signaled whenever the destination format’s largest finite number is exceeded in magnitude by what would have been the rounded floating-point

WebAs you want to do calculations with floating point numbers anyway, I suggest you change at least one of the numbers in each multiplication to float, i.e. 2891000*4450.0, thereby forcing the compiler to cast everything to real before doing the calculation. You probably also want to use double precision, but that’s not your problem here. WebFloating underflow is gradual: denormalized values are produced until the result becomes 0. The -fpe or /fpe option enables exceptions in the Fortran main program only. The floating-point exception behavior set by the Fortran main program remains in effect throughout the execution of the entire program unless changed by the programmer.

WebWhen a serious runtime error is encountered or a deadly signal is emitted (segmentation fault, illegal instruction, bus error, floating-point exception, and the other POSIX signals that have the action ‘ core ’), the Fortran runtime library tries to output a backtrace of the error. -fno-backtrace disables the backtrace generation. http://computer-programming-forum.com/49-fortran/8be730aedbc983e5.htm
