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

    pub unsafe extern "rust-intrinsic" fn float_to_int_unchecked<Float: Copy, Int: Copy>(
        value: Float
    ) -> Int

🔬 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

Convert with LLVM’s fptoui/fptosi, which may return undef for values out of range (https://github.com/rust-lang/rust/issues/10184)

Stabilized as `f32::to_int_unchecked` and `f64::to_int_unchecked`.
