Notes to Financial Statements [Abstract]
Basis of Presentation	1.   Basis of Presentation The accompanying condensed consolidated financial statements for the three month periods ended March 31, 2012 and 2011 are unaudited. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the financial position, results of operations, comprehensive income and cash flows of Roper Industries, Inc. and its subsidiaries ("Roper" or the "Company") for all periods presented. Roper's management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"). Actual results could differ from those estimates. The results of operations for the three month period ended March 31, 2012 are not necessarily indicative of the results to be expected for the full year. You should read these unaudited condensed consolidated financial statements in conjunction with Roper's consolidated financial statements and the notes thereto included in its 2011 Annual Report on Form 10-K ("Annual Report") filed on February 24, 2012 with the Securities and Exchange Commission ("SEC").
