How to compare a string and a numeral
Posted by chirag1184 (chirag1184), 29 May 2008Hi how to compare
a string extracted from some line
and a value or a numeral.
A value 900 is read from a text file needs to be compared to 900.0000000 returned from a statement executed on some machine.
in expect it is compared successfully using ==, while in the script it say the two are unequal.
Posted by admin (Graham Ellis), 29 May 2008Remember that everything in Tcl is held as a string, so 900 won't be equal to 900.00000
Try using expr to subract one from the other and test he result against zero.
Posted by chirag1184 (chirag1184), 30 May 2008Even the expr is not working in subtracting the two, 900 and 900.0000, it works in expect but is not working in the script.
