Weighted Average Shares OutstandingBasic earnings per share were calculated using net earnings and the weighted average number of shares of common stock outstanding during the respective period. Diluted earnings per share were calculated using net earnings and the weighted average number of shares of common stock and potential common stock outstanding during the respective period. Potentially dilutive common stock consisted of stock options based upon the trading price of Roper’s common stock. The effects of potential common stock were determined using the treasury stock method.

Weighted average shares outstanding are shown below:


	Three months ended March 31,
		2023	2022
Basic shares outstanding		106.3	105.6
Effect of potential common stock:
Common stock awards		0.7	1.1
Diluted shares outstanding		107.0	106.7

For the three months ended March 31, 2023, there were 1.150 outstanding stock options, respectively, that were not included in the determination of diluted earnings per share because doing so would have been antidilutive, as compared to 0.840 outstanding stock options that would have been antidilutive in the respective 2022 period.
