+DESCRIPTION
+    If x has a finite decimal representation (with nonzero last digit),
+    places(x) returns the number of digits after the decimal point in this
+    representation; this is the least non-negative integer n for which
+    10^n * x is an integer.
+
+    If x does not have a finite decimal representation, places(x) returns -1.
