[[scaled-float-saturation]]
==== `scaled_float` saturation

`scaled_float` is stored as a single `long` value, which is the product of multiplying the original value by the scaling factor. If the multiplication
results in a value that is outside the range of a `long`, the value is saturated
to the minimum or maximum value of a `long`. For example, if the scaling factor
is +100+ and the value is +92233720368547758.08+, the expected value is +9223372036854775808+.
However, the value that is stored is +9223372036854775807+, the maximum value for a `long`.

This can lead to unexpected results with <<query-dsl-range-query,range queries>>
when the scaling factor or provided `float` value are exceptionally large.
