+<note important>This function is called ''a_GetCVarFixed()'' because it conflicts with [[:GDCC]]'s unrelated ''GetCVarFixed()''.</note>
+===== Description =====
+Returns the value of an int or float CVar as a fixed-point number.
+Returns 0 if the CVar doesn't exist or is not a number.

+int mul = a_GetCVarFixed("mymod_multiplier"); // declared as float in CVARINFO
+int value = FixedMul(x, mul);
+</code>
