# [−][src]Function std::intrinsics::cosf32

    pub unsafe extern "rust-intrinsic" fn cosf32(x: f32) -> f32

🔬 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 the cosine of an `f32`.

The stabilized version of this intrinsic is `std::f32::cos`
