Wish to round float in integer

[pawelf]

Hallo,

i wish to round any float in a integer in a (svg) path.
I try
awk '/[-+]?\d*\.?\d+/ {print int($1+0.5)}' input.svg>output.svg
but the output (in the file) is 0 0.
The regex works fine and the round is tested. What's the problem?

Just to be sure you use the right field you may try this:
print $1, int($1+0.5)

A svgpath look like this
.. d="m78.222,22.069c-1.4335,0.0073-2.8714,0.12168-3.7812, and so on
That's why i use the regex to find all (and only) the floats

With the posted sample, what is the expected result ?

The expected code is:
.. d="m78,22c-1,0-3,0-4,...

Try this:

awk '
        {
                line=[blue]$0[/blue]
                output=[red]"[/red][purple][/purple][red]"[/red]
                [gray]# for every float on the line[/gray]
                [olive]while[/olive] ([b]match[/b](line,[green]/[0-9]+[.]?[0-9]*/[/green])) {
                        [gray]# extract the float from the line[/gray]
                        number=[b]substr[/b](line,[blue]RSTART[/blue],[blue]RLENGTH[/blue])
                        [gray]# insert it into the output line[/gray]
                        output=output [b]substr[/b](line,1,[blue]RSTART[/blue]-1) [b]int[/b](number+0.5)
                        [gray]# save the rest of the line for further processing[/gray]
                        line=[b]substr[/b](line,[blue]RSTART[/blue]+[blue]RLENGTH[/blue])
                }
                output=output line
                [b]print[/b] output
        }
' input.svg > output.svg

It works fine from a file (f.e. awk.sh) but not from the command line.
Can i use it in this way?
awk -f float2integer.awk input.svg>output.svg

I wrote a little zenityscript:

#!/bin/bash
zenity --info --text "With this tool, you can convert the float number in a SVG file in a integer numbers. This will important reduce the size of the file.The convertetd file will save in the same directory like this script."
input=`zenity --title="Select a file" --file-selection --text="name of the file"`
awk '{
                line=$0
                output=""
                # for every float on the line
                while (match(line,/[0-9]+[.]?[0-9]*/)) {
                        # extract the float from the line
                        number=substr(line,RSTART,RLENGTH)
                        # insert it into the output line
                        output=output substr(line,1,RSTART-1) int(number+0.5)
                        # save the rest of the line for further processing
                        line=substr(line,RSTART+RLENGTH)
                }
                output=output line
                print output
        }
' "$input" > output.svg
zenity --info --text 'finished '

This works fine for me.
