| class length( |
f, type="u", unit=None) |
-
The constructor of the length class expects as its first
argument a number f, which represents the prefactor of the given length.
By default this length is interpreted as a user length (
type="u") in units
of the current default unit (see set() function of the unit
module). Optionally, a different type may be specified, namely
"u" for user lengths, "v" for visual lengths, "w"
for width lengths, "x" for TEX length, and "t" for true
lengths. Furthermore, a different unit may be specified using the unit
argument. Allowed values are "cm", "mm", "inch",
and "pt".
Instances of the length class support addition and substraction either by another length
or by a number which is then interpeted as being a user length in
default units, multiplication by a number and division either by another
length in which case a float is returned or by a number in which
case a length instance is returned. When two lengths are
compared, they are first converted to meters (using the currently set
scaling), and then the resulting values are compared.
