# [−][src]Function std::intrinsics::log2f64

    pub unsafe extern "rust-intrinsic" fn log2f64(x: f64) -> f64

🔬 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 base 2 logarithm of an `f64`.

The stabilized version of this intrinsic is `std::f64::log2`
