# [−][src]Function std::intrinsics::wrapping_mul

    pub const extern "rust-intrinsic" fn wrapping_mul<T>(a: T, b: T) -> T

🔬 This is a nightly-only experimental API. (`core_intrinsics`)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Returns (a * b) mod 2N, where N is the width of T in bits.

The stabilized versions of this intrinsic are available on the integer primitives via the `checked_mul` method. For example, `std::u32::checked_mul`
