Detailed Description

In the GMT the concept of a symmetric scale exists The internal representation of scale values is "pseudo-signed", i.e. the highest bit stores the sign and the lower bits contain the absolute value

Attention: for reasons of symmetry, the low edge in this scale is the edge closer to zero. the high edge is the edge further away from zero
