convertdop	convert a doppler velocity quantity to another unit
quantity	make a quantity from a string or from a numeric value and a unit string
getvalue	get the internal value of a quantity
getunit	get the internal unit of a quantity
canonical	get canonical value of quantity
canon	get canonical value of quantity
convert	convert a quantity to another unit
define	define a new unit name
map	list known unit names and constants
maprec	create record containing list of known unit names and constants
fits	define some FITS units

time	show a time (or date) as a formatted string
add	add quantities
sub	subtract quantities
mul	multiply quantities
div	divides quantities
neg	negate quantities

norm	normalise angle
le	compare quantities
lt	compare quantities
eq	compare quantities
ne	compare quantities
gt	compare quantities
ge	compare quantities
sin	sine of quantity
