How can I have a float64 dtype on a 32-bit machine? For example: In [90]: x = array([1/3],dtype=float32) In [91]: x Out[91]: array([ 0.33333334], dtype=float32) In [92]: x = array([1/3],dtype=float64) In [93]: x Out[93]: array([ 0.33333333]) Obviously, the float32 and float64 representations of 1/3 are different, but what is the meaning of float64 on a 32-bit machine? Shouldn't a 32-bit machine only be able represent float32? Thanks!
