Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The fair value of long-term debt was determined using the present value of future cash flows based on the borrowing rates currently available for debt with similar terms and maturities (Level 2 measurement, as described in “Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K for the fiscal year ended October 1, 2017). The carrying value of our long-term debt approximated fair value at July 1, 2018 and October 1, 2017. As of July 1, 2018, we had borrowings of $434.2 million outstanding under our credit agreement, which were used to fund our business acquisitions, working capital needs, stock repurchases, dividends, capital expenditures and contingent earn-outs.
