Function Documentation

const char* bu_units_string (  register const double  mm  )

B U _ U N I T S _ S T R I N G Given a conversion factor to mm, search the table to find what unit this represents. To accomodate floating point fuzz, a "near miss" is allowed. The algorithm depends on the table being sorted small-to-large. Returns - char* units string NULL No known unit matches this conversion factor. Definition at line 161 of file units.c.
