+    j		int
+
+    return	real
+
+DESCRIPTION
+    Truncate x to j binary places.  If j is omitted, 0 places is assumed.
+    Specifying zero places makes the result identical to int().
+
+    Truncation of a non-integer prodcues values nearer to zero.

+EXAMPLE
+    > print btrunc(pi()), btrunc(pi(), 10)
+    3 3.140625
+
+    > print btrunc(3.3), btrunc(3.7), btrunc(3.3, 2), btrunc(3.7, 2)
+    3 3 3.25 3.5
+
+    > print btrunc(-3.3), btrunc(-3.7), btrunc(-3.3, 2), btrunc(-3.7, 2)
+    -3 -3 -3.25 -3.5
