from NonAssociativeAlgebra Fraction Integer

quatern: (R, R, R, R) -> %

quatern(r, i, j, k) constructs a quaternion from scalars.

rational?: % -> Boolean if R has IntegerNumberSystem

rational?(q) returns *true* if all the imaginary parts of q are zero and the real part can be converted into a rational number, and *false* otherwise.

rational: % -> Fraction Integer if R has IntegerNumberSystem

rational(q) tries to convert q into a rational number. Error: if this is not possible. If rational?(q) is true, the conversion will be done and the rational number returned.

rationalIfCan: % -> Union(Fraction Integer, failed) if R has IntegerNumberSystem

rationalIfCan(q) returns q as a rational number, or “failed” if this is not possible. Note: if rational?(q) is true, the conversion can be done and the rational number will be returned.

real: % -> R

real(q) extracts the real part of quaternion q.
