drscheme:rep:use-number-snip in DrScheme Tools Functions

• (drscheme:rep:use-number-snip) -> (any? . -> . boolean?)

  
  

• (drscheme:rep:use-number-snip use-number-snip?) -> void?
     use-number-snip? : (any? . -> . boolean?)

  This is a parameter whose value is a predicate determines if DrScheme uses a mixed fraction snip, a repeating decimal snip, or a regular ASCII improper fraction for printing numbers.

  If the value of the parameter returns #t, a mixed improper fraction snip is used. If it returns 'repeating-decimal, a repeating decimal snip is used. If it returns #f, an ASCII improper fraction is used.

  Its default value is:

  (lambda (x)
     (if (and (number? x)
              (exact? x)
              (real? x)
              (not (integer? x)))
         #t
         #f))
  

  The value of this parameter must not return #t more often than the above code, or else the snip implementation will fail. It may, however, return #f more often.
