Often one is faced with dealing with sets, or ranges of numbers. They can be a pain to parse, as well as to iterate over.
The rangel
family of routines work on ranges of integers.
Parsing of the ranges is done with rangel_parse
. Iterating
through them is done with rangel_next
and rangel_reset
.
There are several routines for manipulating the minimum and maximum
range values.
The rangef
routines work on ranges of real numbers. Parsing
of range specifications is done with rangef_parse
. To
determine if a real is within a range list, use rangef_in
.
Errors are handled via range_perror
.
