Problem with exponentiation: -2**2 gives 4 instead of -4 60 38 (5/22/2009 10:56:41 AM) comp.lang.tcl Hello, I ran into a problem with exponentiation in Tcl 8.5.0: expr {-2**2} gives 4 where I would expect -4 as an answer. If this has been solved in later version, then please ignore this report. (I will have... Arjen

Opening a file in main program and writing to it in a DLL seems impossible under Windows 4 78 (4/27/2009 1:40:00 PM) comp.lang.fortran Hello, we have run into a somewhat awkward problem: We open a file in the main program and one of the routines in a DLL is supposed to write to that same file.

Tcl 8.5 sometimes produces numbers with long fractional parts 7 45 (3/20/2009 6:35:17 PM) comp.lang.tcl Hello, if you compute 0.2*3 in Tcl 8.5 the result is: % expr {0.2*3} 0.6000000000000001 rather than the 0.6 I would have liked to get. It is annoying in the context of Plotchart where sometimes you get labe... Arjen

Experiment: A kind of declarative style 5 62 (2/25/2009 12:11:49 PM) comp.lang.fortran Hi, just a small experiment I would like to share with you: The code below shows that you can pass an expression (well, at least as far as the programmer should be concerned) to a routine for later use.

Recognising NaNs 5 47 (2/23/2009 10:50:31 AM) comp.lang.tcl Hi, since Tcl 8.5 we can deal with Not-a-numbers (NaN) in a systematic way - at least from the scripting side. The problem I currently face (as part of the Tcl interface in the PLplot project - http://plplot.s... Arjen

Intrinsic functions and non-trivial lower bounds 29 51 (2/3/2009 8:00:05 AM) comp.lang.fortran Hello, I have run into issues with lower bounds for arrays other than 1 in the past, in our own subroutines and functions and I understand the behaviour/design choice. However, I found that this behaviour also... Arjen

Can the last record in a direct access file be shorter than the record length? 10 63 (2/3/2009 7:54:18 AM) comp.lang.fortran Hello, I have run into a small issue with direct-access files (within the PLplot project - http://plplot.sf.net). The background: some compilers use record lengths expressed in "words" rather than bytes as th... Arjen
