Modul Python cmath
Modul Python cmath
Python memiliki modul bawaan yang dapat Anda gunakan untuk tugas matematika untuk bilangan kompleks.
Metode dalam modul ini menerima int, float, dan complexangka. Ia bahkan menerima objek Python yang memiliki a __complex__()atau __float__()metode.
Metode dalam modul ini hampir selalu mengembalikan bilangan kompleks. Jika nilai kembalian dapat dinyatakan sebagai bilangan real, nilai kembalian memiliki bagian imajiner 0.
Modul cmathmemiliki seperangkat metode dan konstanta.
