float division in bash

float division in bash

Default Division in BASH is based on Integer Number(s). How can we deal with floating point division in bash ?

In that case "bc" command can be used.

Two types of float division can be done in "bc"

1. Mentioning Scale
2. Full Scale

1. Mentioning Scale

echo "'scale=2; 100/3" | bc 

Will give the output as 33.33 (2 Decimal Spaces)

2. Full Scale

 echo "100/3" | bc -l

Will give the output as33.33333333333333333333
