Officially in the GDA spec, formatting a 0 with any decimal places should be 0. However, this code doesn't do that - it formats the number of 0s up to 6, and then
0E-exponent
afterwards.To make this more "PG" compatible, we fix this by ensuring we display as many 0s as the exponent allows in the
.String()
case.Refs cockroachdb/cockroach#102217, but not 100% sure I like the solution.
