Function patch_seq_f_eq 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_f_eq(stack: Stack) -> Stack

Float equality: ( Float Float – Int )

Warning: Direct float equality can be surprising due to IEEE 754 rounding. For example, 0.1 0.2 f.add 0.3 f.= may return 0. Consider using epsilon-based comparison for tolerances.

Safety

Stack must have two Float values on top
