十进制数转化成二进制数(float)
while True: number=input("请输入一个正数:(输入q退出程序)") if number in ['q','Q']: break elif not float(number)>0: print("请输入一个正数(输入q退出程序):") else: number=float(number) array1=[] array2=[] integer=int(number) floa=number-integer while integer!=0: array1.append(integer%2) integer=integer//2 else: array1.append(0) array1.reverse() while floa>0.00001: array2.append(int(2*floa)) floa=floa*2-int(floa*2) else: array2.append(0) array1.append(".") array=array1+array2 for x in array: print(x,end="") print("\n")
