Summary: In Xcode 9 beta 3, the prefix operator '-' on the Decimal value '0' returns NaN instead of the expected value '0'. The infix operator '0 - 0' works correctly. In Xcode 8.3 both the infix and the prefix operators work as expected. Steps to Reproduce: Create a Playground in Xcode 9 beta 3 containing: import Foundation let zero: Decimal = 0 -zero Expected Results: I expect that the negated 0 is still 0 Observed Results: The negated 0 is NaN Version: Xcode 9 beta 3
