Integer/Float Problem

[danhodges99]

Hi,

I have a script which takes a value from a file and performs calculations on it. Trouble is that this value is a float not an integer and it errors at the decimal point!
eg. 94.62
I would like to be able to detect the length of the float (in this above case, 5 characters), and simply do a cut -c on the first x characters depending on it's length. Anyone know how to detect the length of this input?

Cheers

No problem guys, got it! In case anyone needs to know, you can just bung the variable into a temp file and do a
wc -m ${TEMPFILE}
which gives you the total characters in the file. Ta anyways.

Hi,
if
A=94.62
(for example)
echo ${#A} give 5
I think it is better than create temporary file and count it size.

Another way:

VAR=94.62
len=$(expr "$VAR" : '.*')
echo $len

# or if you prefer:
len=`expr "$VAR" : '.*'`
echo $len
