+### Floating Point Special Values
+
+Spark SQL supports several special floating point values in a case-insensitive
manner:
+
+ * Inf/+Inf/Infinity/+Infinity: positive infinity
+ * ```FloatType```: 1.0f / 0.0f
+ * ```DoubleType```: 1.0 / 0.0
+ * -Inf/-Infinity: negative infinity
+ * ```FloatType```: -1.0f / 0.0f
+ * ```DoubleType```: -1.0 / 0.0
Review comment:
How about describing the infinity semantics, too?
