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

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

T: Copy,

## 🔬 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 2^{N}, 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`
