# [−][src]Function core::intrinsics::floorf32

    pub unsafe extern "rust-intrinsic" fn floorf32(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 largest integer less than or equal to an `f32`.

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