I use bash calculator for floating point calculations and I have to use input redirection and backtick (`) symbol in scripts.
As normal bracket $[math operation]
and expr doesn't support float calculation.
Is there any other way to do float calculation directly instead of using bc in script.
I don't like unnecessary input redirection and backtick (`) symbol for scripts.
#!/bin/bash
x=5
y=6
z=3.3
result=`bc <<end
scale=3
temp_divide=($x / $y)
temp_divide * $z
end`
echo "final result is $result"
