A New Programming Technique for Rational Fractions
K. M. Howell · The Computer Journal · 1959
A method of programming calculations with rational fractions in terms of their prime factors is described. Three storage locations are used to accommodate the exponents of the prime factors up to 103, with an additional location for factors larger than this, or for a zero factor. The application of the technique to calculating Wigner 6j-symbols is outlined.
