Adding variables in bash

I am trying to assign 2 variables floating values and then trying to store the sum in third variable but I get an error.

#!/bin/bash
x=0.1
y=1000.0
z=$((x+y))

echo $z

output is: xyz.sh: 6: xyz.sh: Illegal number: 0.1

I am unable to understand what is going wrong.

I want z to be = 1000.01

BASH doesn't support floating point arithmetic. Use bc command instead:

z=$(bc -l <<< "$x + $y")
echo "$z"
1000.1
