## Description

The relational operators greater than (>), less than (<), greater than or equal (>=), and less than or equal (<=) operate on scalar and vector types [1]. All relational operators result in an integer type. After operand type conversion, the following cases are valid:

• The two operands are scalars. In this case, the operation is applied, resulting in an int scalar.

• One operand is a scalar, and the other is a vector. In this case, the scalar may be subject to the usual arithmetic conversion to the element type used by the vector operand. The scalar type is then widened to a vector that has the same number of components as the vector operand. The operation is done component-wise resulting in the same size vector.

• The two operands are vectors of the same type. In this case, the operation is done component-wise resulting in the same size vector.

All other cases of implicit conversions are illegal.

The result is a scalar signed integer of type int if the source operands are scalar and a vector signed integer type of the same size as the source operands if the source operands are vector types. Vector source operands of type charn and ucharn return a charn result; vector source operands of type shortn and ushortn return a shortn result; vector source operands of type intn, uintn and floatn return an intn result; vector source operands of type longn, ulongn and doublen return a longn result. For scalar types, the relational operators shall return 0 if the specified relation is false and 1 if the specified relation is true. For vector types, the relational operators shall return 0 if the specified relation is false and -1 (i.e. all bits set) if the specified relation is true. The relational operators always return 0 if either argument is not a number (NaN).
