[Numpy-discussion] Inquiry about the difference between numpy.trunc() and numpy.fix()

I am writing to seek clarification on the specific differences between the numpy.trunc() and numpy.fix() functions. I have come across opinions stating that these two functions exist for backward compatibility and that they serve different functional requirements. However, I am puzzled as to why these functions could not be merged or one of them upgraded to encompass both functionalities. Despite my efforts in researching and contemplating on this matter, I have not come across a convincing explanation. Could anyone kindly shed some light on this matter? I am seeking a deeper understanding of the design choices made for these functions and the rationale behind their coexistence. Thank you in advance for your time and assistance.
