tongsmath 1.2.0

Tong's exclusive math library contains some junior high school math functions

tongsmath Function func.py class Func: "To use this class, you need put in a function expressions like 'y=x','y=2x','y=x**2+x+3'(It must be in the form of y=x)" def init(self, evl -> function expressions, st=-100 -> x minimum value, ed=100 -> x maximum value, xlwlim=-100 -> The x-axis minimum, xuplim=100 -> The x-axis maximum, ylwlim=-100 -> The y-axis minimum, yuplim=100 -> The y-axis maximum) def show(self) : Displays the function image Primenumber DPF.py def DPF(n)->list or bool :Returns the prime factor (list) of n,if b is prime number return False. e.g. DPF(48)->[2,2,2,2,3] means 48 = 2222*3 DPN.py def prime_number_list(n)->list or bool :Returns all prime numbers within n, if there is no content in the prime number list return False. def is_primenumber(n)->bool :Returns whether n is prime.

Simplify
    sim2ndrt.py
                def sim2ndrt(n)->list or int :Returns the simplified result of sqrt(n).
                                           e.g. sim2ndrt(12)->[2,3] means sqrt(12) = 2 * sqrt(3)
