Function lexicon_fractional_index::float64_approx[][src]

pub fn float64_approx(key: &str) -> Result<f64, String>
Expand description

float64_approx converts a key as generated by key_between() to a float64. Because the range of keys is far larger than float64 can represent accurately, this is necessarily approximate. But for many use cases it should be, as they say, close enough for jazz.
