Function DecodeFloatDescending

pkg/util/encoding/float.go:89–98

DecodeFloatDescending decodes floats encoded with EncodeFloatDescending.

(buf []byte)

// DecodeFloatDescending decodes floats encoded with EncodeFloatDescending.

		// we have to negate them back. Negative zero uses composite indexes to
		// decode itself correctly.
