Fixed a \-escape bug in calc(1) man page.
Added cal/comma.cal:
Convert numbers into strings with 3-digit group and integer-fraction
separators.
If the value is an integer, the integer-fraction separator is not used.
str_comma(x, [group, [decimal]])
Convert x into a string.
If group is given and is a string, group will be used as
the 3-digit group separator, otherwise the default 3-digit
group separator will be used.
If decimal is given and is a string, group will be used as
the integer-fraction separator, otherwise the default
integer-fraction separator will be used.
The decimal and group arguments are optional.
set_default_group_separator(group)
Change the default 3-digit group separator if group is a string,
otherwise the default 3-digit group separator will not be
changed. Return the old 3-digit group separator.
set_default_decimal_separator(decimal)
Change the default 3-digit group separator if decimal is a
string, otherwise the default integer-fraction separator
will not be changed. Return the old integer-fraction separator.
print_comma(x, [group, [decimal]])
Print the value produced by str_comma(x, [group, [decimal]])
followed by a newline.
If the str_comma() does not return a string, nothing is printed.
The decimal and group arguments are optional.
The value produced by str_comma() is returned.
fprint_comma(fd, x, [group, [decimal]])
Print the value produced by str_comma(x, [group, [decimal]]),
without a trailing newline, on file fd.
If the str_comma() does not return a string, nothing is printed.
If fd is not an open file, nothing is printed.
The decimal and group arguments are optional.
The value produced by str_comma() is returned.
