A115369: Decimal expansion of first zero of the Bessel function

J1(z)

.

3.8317059702075...

According to Eric Weisstein, this is also the first zero of

J0′ (z)

rather than 0 as given by Abramowitz and Stegun in their landmark Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables. Mathematica also gives this constant rather than 0 as the first zero of this function.
