Function core::intrinsics::exp2f32

pub unsafe extern "rust-intrinsic" fn exp2f32(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

返回 2 乘以 f32 的幂。
