[Haskell-beginners] Why are the types of the result different?

[Russ Abbott]

testWhere1 = a
             where b = 1
                      a = b+1

> testWhere1
 2

testWhere2 = a
             where b = 1
                      c = 1/(b - b)
                      a = b+1

> testWhere2
 2.0

The same thing happens with let.

testLet1 = let a = b+1
                         b = 1
               in a

> testLet1
2

testLet2 = let a = b+1
                   c = 1/(b - b)
                   b = 1
               in a

> testLet2
2.0
