Can the same mathematical operation return different results in different architectures or browsers ?
Although the ECMAScript language specification 5.1 edition states that numbers are primitive values corresponding to IEEE 754 floats, which implies calculations should be consistent:

As BlueRaja points out, there is a sort of caveat in section 15.8.2:
Meaning, these are at least some cases where the outcome of operations on numbers is implementation dependent and may therefore be inconsistent.
