`+` (unary plus) operator

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

Usage

Integer one = +1;

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

Integer minusOne = +(-1);

The + operator is defined as follows:

rhs.positiveValue;

See the language specification for more details.

The unary + operator is polymorphic. The meaning of + depends on Invertible interface

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

For the built-in numeric types Integer and Float, + is essentially a no-op.
