+
+The rounding mode for floating-point arithmetic is characterized by the
+values:
+
+- [(1.1)](#1.1)
+
+round_indeterminate if the rounding style is indeterminable
+
+- [(1.2)](#1.2)
+
+round_toward_zero if the rounding style is toward zero
+
+- [(1.3)](#1.3)
+
+round_to_nearest if the rounding style is to the nearest representable value
+
+- [(1.4)](#1.4)
+
+round_toward_infinity if the rounding style is toward infinity
+
+- [(1.5)](#1.5)
+
+round_toward_neg_infinity if the rounding style is toward negative infinity
