pub fn f64_117(bits: impl FnMut() -> u64) -> f64Expand description
Returns a random f64 distributed as a uniform 117-bit fixed-point real
in [0 . . 1) rounded down to the nearest representable value: every
float in [2⁻⁶⁵ . . 1), and the multiples of 2⁻¹¹⁷ below 2⁻⁶⁵.
A port of Float64_117: as f64_64, except that when the first word
has 12 or more leading zeros (probability 2⁻¹²) a second word extends the
fixed point to 117 bits.
