Miscellaneous-NoPrecisionLoss

Do not assign longer data types to shorter ones

Required inputs: IR

This rule will warn on implicit conversions from larger types to shorter types. Use an explicit conversion to make it clear that the conversion may cause loss of precision.

Example

short int_to_short(int i)
{
    return i; // BAD

    return (short)i; // OK
}

Possible Messages
