Compute the exponentially-scaled modified spherical Bessel
function of the first kind and order 1,
is(1,x).
The modified spherical Bessel functions provided by these software
implementations are defined according to Chapter 10, Bessel
Functions of Fractional Order, of the Handbook of Mathematical
Functions, edited by Milton Abramowitz and Irene A. Stegun,
National Bureau of Standards Applied Mathematics Series #55, US
Department of Commerce, Washington, DC (1964).
Although in mathematics, uppercase letters name the ordinary and
modified Bessel functions, and lowercase letters name the spherical
Bessel functions, the lowercase names of the POSIX Bessel functions
mean the former, not the latter.
If the argument is finite, its exponentially-scaled modified spherical
Bessel function value of the first kind and order 1 is returned.
Otherwise, a quiet NaN is returned.
If the argument is a NaN, errno is set to EDOM, and that
NaN is returned.
