Many thanks (Ken) for the bug report and (John) for the investigation. This has now been fixed for the next release of FTN95.

If "implicit none" is added to the main program, FTN95 ought to fault the use of the variables a and dp.

It fails in this respect and I will note this as a bug that needs fixing.

64 bit applications can in theory access the the x87 FPU coprocessor which has 80 bit floating point precision. This coprocessor is separate from the the CPU that uses SSE etc. instructions and which ...

This omission has now been fixed for the next release of the DLLs.

64 bit executables are not generally the answer to issues relating to floating point precision.

For example 32 bit FTN95 provides for 80 bit floating point values as well as 32 and 64. Most Fortran ...

For maximum precision you can use real*10 with Win32 rather than x64.

options(alt_kinds)
program main
real*10 :: a,b,c,d
logical :: f1, f2
a = 1.0_10/3.0_10
b = 2.0_10/ ...

I don't have Linux installed but I will take a look at EPOCH when I can.

John

I will aim to add LOCAL etc. so that FTN95 will not raise an error condition when these attributes are added ...

If you are aready doing parallel processing but not with FTN95 perhaps you would send me the project so that I can get an idea of what you are asking for.

In the mean time FTN95 with ClearWi ...

There are various ways in which we (Silverfrost) can deploy our resources:

1) Bug fixing.
2) Implementing new features in the Fortran Standards.
3) Implementing on operating systems other than Wi ...

This has now been added for the next release of FTN95 and the DLLs.

program main
real*8 a,b,c
a = 0.0d0
b = 0.0d0
c = 0.0d0
iw = winio@("%co[check_on_focus_loss]&")
iw = winio@("%nlA: %rf[fmt=7.2g]&", a ...

I have had a look at this code and FTN95 appears to be conforming to the Standard in this case.

Kenneth

Thank you for the suggestion. I have added this to the list.

Thank you for the bug report. I have logged this as needing fixing.

In general when a user types in a fp number it will contain digits, possible full stop, signs and E or e. Only when they have finished can ClearWin+ read and then present the number in the requested f ...
