- ) Page 57 of the TeXbook says the following:
- ) pt point
- ) pc pica (1 pc = 12 pt)
- ) in inch (1 in = 72.27 pt)
- ) bp big point (72 bp = 1 in)
- ) . . .
- ) sp scaled point (65536 sp = 1 pt)
-
- ) Don't ask me what (or what use) a scaled point is.
-
- TeX does all its internal calculations in scaled points, giving
- more than enough precision for any practical purpose.
-
- Note also that TeX's big point (bp) corresponds exactly to
- what many other systems and typesetting languages, including
- PostScript, call a point.
