# Numeric Protocols Write generic code that works with any numeric type. ## Topics ### Basic Arithmetic [`AdditiveArithmetic`](/documentation/Swift/AdditiveArithmetic) A type with values that support addition and subtraction. [`Numeric`](/documentation/Swift/Numeric) A type with values that support multiplication. [`SignedNumeric`](/documentation/Swift/SignedNumeric) A numeric type with a negation operation. [`Strideable`](/documentation/Swift/Strideable) A type representing continuous, one-dimensional values that can be offset and measured. ### Integer [`BinaryInteger`](/documentation/Swift/BinaryInteger) An integer type with a binary representation. [`FixedWidthInteger`](/documentation/Swift/FixedWidthInteger) An integer type that uses a fixed size for every instance. [`SignedInteger`](/documentation/Swift/SignedInteger) An integer type that can represent both positive and negative values. [`UnsignedInteger`](/documentation/Swift/UnsignedInteger) An integer type that can represent only nonnegative values. ### Floating Point [`FloatingPoint`](/documentation/Swift/FloatingPoint) A floating-point numeric type. [`BinaryFloatingPoint`](/documentation/Swift/BinaryFloatingPoint) A radix-2 (binary) floating-point type. ### Floating-Point Characteristics [`FloatingPointClassification`](/documentation/Swift/FloatingPointClassification) The IEEE 754 floating-point classes. [`FloatingPointRoundingRule`](/documentation/Swift/FloatingPointRoundingRule) A rule for rounding a floating-point number. [`FloatingPointSign`](/documentation/Swift/FloatingPointSign) The sign of a floating-point value. --- Copyright © 2026 Apple Inc.
