# hybrid(precision:explicitPositiveSign:uppercase:) Creates a custom hybrid format with the precision value. ``` static func hybrid(precision: @autoclosure @escaping () -> Int, explicitPositiveSign: Bool = false, uppercase: Bool = false) -> OSLogFloatFormatting ``` ## Parameters `precision` The maximum number of digits to display to the right of the decimal point. `explicitPositiveSign` A Boolean value that indicates whether to display a plus (`+`) sign in front of positive numbers. `uppercase` A Boolean value that indicates whether to uppercase letters that are part of the floating-point number. For example, it determines the capitalization of the exponent indicator `e` in the number `1.0e9`, or the letters in special values such as `NaN` and `Inf`. ## Return Value A custom hybrid format for floating-point numbers. --- Copyright © 2026 Apple Inc.
