# Parse fractional JSON numbers with serde_json's correctly-rounded float parser, so that
# numeric flag values and numeric context attributes deserialize to the same f64 that Go's
# encoding/json produces. This keeps evaluations consistent with the other LaunchDarkly SDKs
# and is why the feature is enabled by default.
#
# Disabling it makes serde_json use its faster best-effort parser, which can land one unit in
# the last place away from the correctly-rounded value. Note that Cargo feature unification is
# additive and global, so this feature is still on if any other crate in the dependency graph
# asks for serde_json/float_roundtrip.
