Bash use ONLY INTEGER numbers!
Read man bash!
TOT=21765 NUM=`echo $TOT / 1000 |bc -l` echo "$TOT $NUM"
But don't be fooled, $NUM is a string, not a floating point number
Yes. You can install 'bc' to do more math in scripts, for example:
R=$(echo 'scale=3;21765/1000' | bc -l) echo $R
One drawback: it has no rounding, only truncation, so you'd have to improvise with +0.5 or use printf.
In Javascript and many other languages, there is no difference.

Irrelevant. The topic of this conversation is Bash, not javascript nor "many other languages".
Your digression seems meant only to confuse the issue under discussion.

Also it?s wrong. Strings and numbers are distinct types in JS.

They are typed, but it's weak rather than strong, and has automatic promotion
str = "1.570795"; num = 1.570795; res = 2 * str; alert([typeof(str), typeof(num), res, typeof(res)]);
A. Dumas:
Or you can keep truncation, but set up one extra digit of precision...

How does that help?
echo 'scale=4;1/3*3' | bc -l
