Converts a `u32` to a `char`, ignoring validity. Use `char::from_u32_unchecked` instead.

Raises an `f32` to an integer power.

Returns the base 2 logarithm of an `f32`.

Returns whether we should perform some overflow-checking at runtime. This eventually evaluates to `cfg!(overflow_checks)`, but behaves different from `cfg!` when mixing crates built with different flags: if the crate has overflow checks enabled or carries the `#[rustc_inherit_overflow_checks]` attribute, evaluation is delayed until monomorphization (or until the call gets inlined into a crate that does not delay evaluation further); otherwise it can happen any time.

Returns the exponential of an `f32`.

Float subtraction that allows optimizations based on algebraic rules. Requires that inputs and output of the operation are finite, causing UB otherwise.

Raises an `f64` to an `f64` power.

Magic intrinsic that derives its meaning from attributes attached to the function.

API documentation for the Rust `Goto` fn in crate `std`.

Logical “ors” all elements together.
