Hi Enrique,

your advice about the renumbering of nodes was very useful.
I have a question about specifying a certain format for floating point and integer values in tcl. I would like to prescribe floating point and integer format for certain values that I need to write into a file. I need also to transform certain integer values into floating point values and vice versa. I tried to figure out the tcl command for these operations, but I couldn't find any except the command format which is used for strings.
What tcl command allows these operations?

thanks for your response,

Andreas Friedberg

The tcl command is format, the format string is any valid C printf format. for example:
format "%lf" 3.5
3.5 must be a float
to truncate a float to a integer use expr to evaluate a mathematical expression:
expr int(3.5)

to get a real value from an integer:

for expresions:

set int_value 1234
set res [ expr log( double( $int_value))]

for format, you can do this too:

format "%f" $int_value
