Hello Rajeev,
The strongly advised workaround is to use xsd:doublePrecision instead of
xsd:float. The problem with float is that it is not enough precise.
Depending on hardware platform and C library used by compiler same
literal can be parsed and then printed as, say, "4.1299999999" or
"4.13", sooner or later it results in weird errors. Say, one see
"4.1299999999" in the output and tries to delete it from graph and the
request deletes nothing. The issue was so annoying that we suspended
this support temporarily. Probably it will be fixed by converting all
xsd:floats into xsd:doublePrecision literals; but that will raise some
other error -- unexpected return values of DATATYPE() SPARQL built-in
function.
