Improved results in GHCi during basic calculations
We can use GHCi as a calculator using +, -, *,
/, sin, cos, and others.
sometimes the result does not meet our expectations.
for example if I calculate 3 + 2, the result is 5 and in line with our expectations. \\
Prelude> 3+2
5but sometimes it is not.\\ for the two examples below, please, can we have in GHCi a result other than the one given?\\
Prelude> exp(log(1000)-log(10))
99.99999999999996can we have a result equal to 100? \\
Prelude> 12*(1/3-1/4)-1
-2.220446049250313e-16can we have a result equal to 0? \\
