Hi there
With shell script I'm trying to split the string into two parts. One is alphanumeric part, the other one is a numeric part.
dummy_postcode_1 = 'SL1'
--> res_alpha = 'SL' and res_numeric = '1'
dummy_postcode_2 = 'S053'
--> res_alpha = 'S' and res_numeric = '053' ... (1 Reply)
Okay I will let users input spaces as well :)
I am having a mental block. I have done a couple of searches but havent found anything that I understand (the likes of :alpha: and awk).
Basically I want to give the user an option to enter some text which will go down as a field within a flat... (3 Replies)

Hi,
I would like to be able to parse out a substring matching a basic pattern, which is a character followed by 3 or 4 digits (for example S1234 out of a larger string). The main string would just be a filename, like Thisis__the FileName_S1234_ToParse.txt. The filename isn't fixed, but the... (2 Replies)

tcl_printdouble
Tcl_PrintDouble(3) Tcl Library Procedures Tcl_PrintDouble(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_PrintDouble - Convert floating value to string
SYNOPSIS
#include <tcl.h>
Tcl_PrintDouble(interp, value, dst)
ARGUMENTS
Tcl_Interp *interp (in) Before Tcl 8.0, the tcl_precision variable in this interpreter controlled the conversion. As of Tcl 8.0,
this argument is ignored and the conversion is controlled by the tcl_precision variable that is now shared
by all interpreters.
double value (in) Floating-point value to be converted.
char *dst (out) Where to store the string representing value. Must have at least TCL_DOUBLE_SPACE characters of storage.
_________________________________________________________________DESCRIPTION
Tcl_PrintDouble generates a string that represents the value of value and stores it in memory at the location given by dst. It uses %g
format to generate the string, with one special twist: the string is guaranteed to contain either a "." or an "e" so that it does not look
like an integer. Where %g would generate an integer with no decimal point, Tcl_PrintDouble adds ".0". |
If the tcl_precision value is non-zero, the result will have precisely that many digits of significance. If the value is zero (the |
default), the result will have the fewest digits needed to represent the number in such a way that Tcl_NewDoubleObj will generate the same |
number when presented with the given string. IEEE semantics of rounding to even apply to the conversion.
