Details:
taking the logarithm of a quaternion with only a positive real component(ex.
(2, 0i, 0j, 0k)) causes the built in logarithm function of the quaternion
package to return the coefficients of the unreal components as NaN. Based on
my understanding of complex numbers, the coefficients should be set to 0 since
taking the logarithm of a complex number with 0 imaginary components is
equivalents to taking the logarithm of a real number.
