Human interface to make a unit.
Function to define quantities without the reader macro.
Shadow the global unit table with a new rule table.
Shadow the global unit table with a copy of the unit table. When returninng from the body the original units are restored.
Lets the user define the #q(...) and #u(...) read macros.
Machine interface for making a unit.
Computes the square root of a given quantity. Result must always be real.
Prints the given unit in human readable form
Checks whether an object is a unit.
Expands and reduces both units and compares the unit factors for equality (in unit and power)
Reduces both units (without converting to base units) and compares the unit factors for equality (in unit and power)
Reduces both units (converting to base units) and compares the unit factors for equality (in unit and power)

Like (error ...), but allows the condition type to be specified (which is required to inherit from simple-condition).
Helper for the inverf function.
Evaluates the nth Chebyshev polynomial.
Recursion function for the Chebyshev polynomial evaluation.
Applies the conversion factor between unit-a and unit-b to the given value.
Creates a copy of the given hash table.
Creates a copy of the given unit.
Defines a new unit with the identifier name. A list of aliases and a list of abbreviations are permitted which - when encountered - are internally converted to the primary identifier. The definition allows the unit to be defined in terms of other units, e.g :def (1.602 kilometre). Prefixes is must be a function of two parameters, the base and the power, with which it decides whether a prefix is allowed for the unit. It defaults to allowing all defined prefixes.
Defines a unit prefix such as kilo in kilometre. Apart from the name the power is required (3 for kilo) together with the base that defaults to 10. An abbreviation for the prefix is also allowed which will be used in combination with abbreviated units.
Takes a unit and looks up aliases and abbreviations of unit factors and replaces them with the main unit designators.
Divides the given units with each, reducing the result.
Calculates the error function.
Checks whether a quantity is without uncertainty/error.
Expands the given unit into base units and reduces them
Converts a single unit factor into its expansion of base units, together with a conversion factor
Checks whether a quantity has uncertainty/error.
Checks whether the given quantity has a unit.
Inverse error function.
Tests efficiently whether the length of the list is equal to the given length.
Tests efficiently whether the length of the list is greater than the given length.
Tests efficiently whether the length of list-a is equal to the length of list-b.
Makes a list out of the given object unless it already is a list.
Multiplies units with each other and reduces the result.
Raises the unit to the given power.
Pythagorean addition
Calculates the quantile for the normal distribution.
Helper for the inverf function.
Helper for the inverf function.
The read macro #q(...) is an abbreviation for (quantity ...) which does not transform lowercase symbols to uppercase for unit factors.
The read macro #u(...) is an abbreviation for (mkunit ...) which does not transform lowercase symbols to uppercase.
Reduces the powers of duplicate unit factors in a given unit, e.g. km^2 / km -> km, but m / km -> m / km. No unit lookup is made.
Extracts the root from the given unit if possible. Converts to base units if necessary.
Sorts the unit by positive and negative powers.
Checks whether the given quantity is unitless.
Generic error for quantity definitions.
Semantic error in the definition of a quantity/unit
Syntax error in the definition of a quantity/unit
