+ (unary plus) operator

The right-associative, unary prefix + operator is used to clarify the positive value of its operand.

Usage

Integer one = +1;

Description

Note that + does not change the sign of a negative number:

Integer minusOne = +(-1);

Definition

The + operator is a no-op.

See the language specification for more details.

Type

The result type of the + operator is the same as the Invertible type of its operand.
