Static J1_ZEROS_VALUE 

pub(crate) static J1_ZEROS_VALUE: [u64; 48]

Precomputed values in exact Bessel J1 zero.

Generated by MPFR:

let mut arr = vec![];
for zeros in J1_ZEROS.iter() {
    let mpfr = Float::with_val(107, f64::from_bits(zeros.1)).j1();
    arr.push(mpfr.to_f64().to_bits());
}
println!(
    "arr: [{}]",
    arr.iter()
        .map(|x| format!("0x{:016X}", x))
        .collect::<Vec<_>>()
        .join(", ")
);
