Notes to Financial Statements [Abstract]
Debt	10.   Debt Roper's 3.75% senior subordinated convertible notes due 2034 became convertible on January 15, 2009.  During the nine month period ended September 30, 2011, 58,430 notes were converted for $25.1 million in cash and 433,567 shares of common stock at a weighted average share price of $83.71.  No gain or loss was recorded upon these conversions.  In addition, a related $4.1 million deferred tax liability associated with excess deductions recorded for tax purposes was relieved to additional paid-in capital upon the conversions. At September 30, 2011, the conversion of 1,200 notes was pending with a settlement date of October 6, 2011.  The conversion resulted in the payment of $0.5 million in cash and the issuance of 7,586 shares of common stock at a weighted average share price of $70.12. At September 30, 2011, the conversion price on the outstanding notes was $436.81.  If converted at September 30, 2011, the value would exceed the $68 million principal amount of the notes by $70 million and would result in the issuance of 987,143 shares of Roper's common stock.
