Notes to Financial Statements [Abstract]
Debt	8.   Debt Roper's 3.75% senior subordinated convertible notes due 2034 became convertible on January 15, 2009.  During the three month period ended March 31, 2012, 14,236 notes were converted for $12.9 million in cash and 41,678 shares of common stock at a weighted average share price of $94.50.  No gain or loss was recorded upon these conversions.  In addition, a related $1.1 million deferred tax liability associated with excess deductions recorded for tax purposes was relieved to additional paid-in capital upon the conversions. On March 31, 2012, the conversion of 4,920 notes was pending, with a settlement date of April 3, 2012.  The conversion resulted in the payment of $6.2 million in cash. At March 31, 2012, the conversion price on the outstanding notes was $445.03.  If converted at March 31, 2012 the value would exceed the $62 million principal amount of the notes by approximately $107 million and could result in the issuance of 1,077,835 shares of Roper's common stock.
