	3810	Implicit conversion: double to char.

Arithmetic type - Implicit conversions

An expression of type double is being implicitly converted to 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 2017,3199,3203,3408,3447,3602,3625 ++*/

extern double dbx;
extern void ef(char p);

extern void foo(void)
{
    char pca;

    pca = dbx;                  /* Message 3810 */

    ef(dbx);                    /* Message 3810 */
}
