bash string to float code example

Example 1: bash float

bc <<< '0.3333+0.6666' # Get sum of floats in bash.
0.99			#Same for Substraction and Multiplication
bc -l <<< '10/3' # Fast way to get division
3.33333333333333333333
bc <<< 'scale=2; 10/3' #Define also how many decimals to take in scale
3.33

Example 2: bash adding floats

#Just use following structure for summing up varibles:
sum=$((var1 + var2))
#For float numbers use next instruction:
sum=$(bc <<< $var1'+'$var2)
