 Certain mathematical comparisons will always return the same value, and should simply not be made. 
 
-These comparisons will always return ``++false++``:
+These comparisons will always return `false`:
 
-* comparing a `char` with a numeric constant that's outside the `char` range
-* comparing a `float` with a numeric constant that's outside the `float` range
-* comparing a `long` with a numeric constant that's outside the `long` range
-* comparing a `ulong` with a numeric constant that's outside the `ulong` range
+* Comparing a `char` with a numeric constant that is outside of the range of `char`.
+* Comparing a `float` with a numeric constant that is outside of the range of `float`.
+* Comparing a `long` with a numeric constant that is outside of the range of `long`.
+* Comparing a `ulong` with a numeric constant that is outside of the range of `ulong`.

 float f = 42.0f;
-const double d = double.MaxValue;
-if (f <= d) { } // Noncompliant
+if (f <= double.MaxValue) { } // Noncompliant
