# Units are defined by an optional quantity and an equivalent unit or unit
|
||||||
|
# combination. A python expression may be used for the quantity, but is
|
||||||
|
# resticted to using only the following operators: *, /, +, -, **, (, ).
|
||||||
|
# Beware of integer division truncation: be sure to use a float for at
|
||||||
|
# least one of the values.
|
||||||
|
#
|
||||||
|
# The unit type must be placed in square brackets before a set of units.
|
||||||
|
# The first comment after the equivalent unit will be put in parenthesis after
|
||||||
|
# the unit name (usually used to give the full name of an abbreviated unit).
|
||||||
|
# The next comment will be used in the program list's comment column;
|
||||||
|
# later comments and full line comments are ignored.
|
||||||
|
#
|
||||||
|
# Non-linear units are indicated with an equivalent unit in square brackets,
|
||||||
|
# followed by either equations or equivalency lists for the definition.
|
||||||
|
# For equations, two are given, separated by a ';'. Both are functions of
|
||||||
|
# "x", the first going from the unit to the equivalent unit and the second
|
||||||
|
# one in reverse. Any valid Python expression returning a float (including
|
||||||
|
# the functions in the math module) should work. The equivalency list is a
|
||||||
|
# python list of tuples giving points for linear interpolation.
|
||||||
|
#
|
||||||
|
# All units must reduce to primitive units, which are indicated by an '!'
|
||||||
|
# as the equivalent unit. Circular refernces must also be avoided.
|
||||||
|
#
|
||||||
|
# Primitive units: kg, m, s, K, A, mol, cd, rad, sr, bit, unit
