MPL3115A2 Digital Altitude / Pressure / Temperature Sensor Readings

I am getting some odd reading from this sensor using the Espruino module (https://www.espruino.com/MPL3115A2).

When I run the example code, I get these reading:

Pressure 442.25 pa
Altitude 110.125 m
Temperature 17.6875 C

If I run the sam sensor hooked to an Arduino board, I get these readings:

100158.25 P
97.50 M
15.69 C

The Arduino readings seem to be correct.

Any ideas?
