[previous] 3999 [next] float value returned from char %s().
Arithmetic type - Implicit conversions

An expression of type float is the return expression in a function that returns a value of type plain char. Any implicit conversion from a floating type to an integral type may result in a loss of precision as the fractional element of the value is discarded. If the integral element of the value cannot be represented, the result will be meaningless.

However converting a floating type to a plain char type is even more suspect. Is this really intended ? Type char should be reserved for character data.

For example: 


/*PRQA S 2017,3408,3447,3602,3625 ++*/

extern float v;

extern char foo ( void )
{
    /* ... */
    return(v);                          /* Message 3999 */
}
