MAAB guideline : na_0002: Appropriate implementation of fundamental logical and numerical operations

Hello everybody,

The MAAB guideline na_0002: Appropriate implementation offundamental logical and numerical operations. Indicates that logical data type shouldn't be used in numerical operations. Among the rationales listed, we can see Code generation, but i can't understand how using logical data type in numerical operations could affect negatively Code generation, since a cast is done for the logical data type ?

Any help please.

Regards
