# abs method

Byte abs()

Returns the absolute value of this Byte.

For single bytes only.

Example:

    final b1 = Byte(-42);
    final b2 = Byte(42);

    print(b1.abs().value);  // 42
    print(b2.abs().value);  // 42

Throws NoGuaranteeException if this represents multiple bytes.

## Implementation

    Byte abs() {
      if (!isSingleByte) {
        throw NoGuaranteeException('Cannot get absolute value of byte array');
      }
      return Byte(_bytes[0].abs());
    }
