[][src]Function core::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
