The range of a TeX dimen is precisely (in units of pt) +% [ -(2^30-1) / 2^16, (2^30 -1) / 2^16 ] = [-16383.99998, 16383.99998] +% +% Thus, for an input dimen x, we set up the mapping +% phi(x) = 2^16 * x * 2 +% which maps +% phi: [ -(2^30-1) / 2^16, (2^30-1) / 2^16 ] -> [-(2^31 -2), 2^31-2]. +% +% I simply use the \pgfplotsbinaryencodesignedmaplinearly to process +% this further.
