Function Documentation

btyp_mixed_numeric()

builtin_type_t btyp_mixed_numeric	(	builtin_type_t	x,
		builtin_type_t	y
	)

Determine the resulting type for a possible mixed-type operation.

Rules for the resulting type:

• bool -> double
• single + double -> single
• real + complex -> complex
• integer + real -> integer
• uint + uint -> uint (the bigger one)
• sint + sint -> sint (the bigger one)

Returns

The resulting type or "unknown type", if the resulting type cannot be determined.
