+Checked Arithmetic
+=================
+
+{{#include ../links.md}}
+
+By default, all arithmetic calculations in Rhai are _checked_, meaning that the script terminates
+with an error whenever it detects a numeric over-flow/under-flow condition or an invalid
+floating-point operation, instead of crashing the entire system.
+
+This checking can be turned off via the [`unchecked`] feature for higher performance
+(but higher risks as well).
