Section 3.3.1.3.3. Rotation
aMRC Laboratory of Molecular Biology, Hills Road, Cambridge CB2 2QH, England |
Rotation about the origin is achieved by in which R is an orthogonal matrix. R necessarily has elements not exceeding one in modulus. For machines using integer arithmetic, therefore, N would be chosen large enough (usually half the largest possible integer) for the product NR to be well represented in the available word length. Characteristically, N affects resolution but not scale.
