Income Tax Disclosure [Abstract]  
Income Taxes Income TaxesThe provision for income tax was an expense of $28.9 million and $55.1 million in the three and six months ended October 31, 2022, with an effective tax rate of 27.9% and 26.5%, respectively, compared to an expense of $26.1 million and $50.0 million in the three and six months ended October 31, 2021, with an effective tax rate of 25.5% and 24.7%, respectively. In addition to the impact of U.S. state income taxes and the jurisdictional mix of earnings, which generally create variability in our effective tax rate over time, the effective tax rate for the three and six months ended October 31, 2022 were affected by a tax expense recorded for withholding taxes that are not eligible for credit.
