  or regular expression comparison.
  The first argument is the pattern and the second the string to compare.
- An optional third argument specifies flags:

  For example:

+ Numeric operators may be performed by prefixing two comma-separated alternatives with an
+ .Ql e
+ and an operator.
+ An optional
+ .Ql f
+ flag may be given after the operator to use floating point numbers, otherwise integers are used.
+ This may be followed by a number giving the number of decimal places to use for the result.
+ The available operators are:
+ addition
+ .Ql + ,
+ subtraction
+ .Ql - ,
+ multiplication
+ .Ql * ,
+ division
+ .Ql / ,
+ and modulus
+ .Ql m
+ or
+ .Ql %
+ (note that
+ .Ql %
+ must be escaped as
+ .Ql %%
+ in formats which are also expanded by
+ .Xr strftime 3 ) .
+ For example,
+ .Ql #{e|*|f|4:5.5,3}
+ multiplies 5.5 by 3 for a result with four decimal places and
+ .Ql #{e|%%:7,3}
+ returns the modulus of 7 and 3.

  A limit may be placed on the length of the resultant string by prefixing it
