Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rates for the three- and nine-month periods ended January 31, 2023 were 25.0% and 25.1%, respectively, compared with 26.0% and 26.3%, respectively, in the comparable periods in the prior fiscal year. The effective rates were higher than the 21.0% U.S. statutory rate for the three- and nine-month periods ended January 31, 2023 primarily due to state income taxes. The effective rate for the periods ended January 31, 2023 was lower than the comparable periods in the prior fiscal year primarily due to unfavorable uncertain tax position booked in the comparable periods and an increase in tax credits for the current period.
