When using doubles, why isn't (x / (y * z)) the same as (x / y / z)? [duplicate]

Answer 1

Certainly the order of the operations mixed with the fact that doubles aren't precise :

450.00d / (7d * 60) --> a = 7d * 60 --> result = 450.00d / a

vs

450.00d / 7d / 60 --> a = 450.00d /7d --> result = a / 60
