Don't cast GPS times to float when writing segments to LIGO_LW (!537) · Merge requests · Duncan Macleod / gwpy

Duncan Macleod requested to merge github/fork/duncanmmacleod/ligolw-segments-ligotimegps into develop Sep 14, 2017

This PR fixes a precision issue when writing segments to LIGO_LW XML format. Casting to float loses precision compared to LIGOTimeGPS. I think this was an issue when attempting to cast directly from numpy.float64 to glue.lal.LIGOTimeGPS, but we don't use the glue object any more, so this shouldn't be a problem any more.
