text: # Hexadecimal
  '''
  To use this function you can simply write hex(), within paranthesis 
  put any number, and get hexa decimal coverted number.
  '''
  #a=int(input('enter your number to convert into hexa:    '))
  #print(f'The hexa decimal value of {a}:' + hex(a) +'\n')
  
  #   Binary
  '''
  To convert any number into binary simply use bin(),
  put any value within paranthesis
  '''
  #b=int(input('Enter any number to convert into binary:   '))
  #print(f'The binary value of {b}:    '+bin(b)+'\n')
  
  #   Exponentials
  '''
  This function pow() take two arguments, a to the power y and third is mode
  (x^y)%z
  '''
  #c1=int(input('Enter any integer value:  '))
  #c2=int(input('Enter the power:  '))
  #c=pow(c1,c2)
  #print(f'The {c1} of power {c2} is equal:    {c}'+'\n')
  
  #print(pow(5,2,3))
  #so now here 5 is the value we need their to multiply,2 is power, and 3 is mode
  
  #   Absolute Value
  '''
  This will return absolute value of a number.Argument can be int,
  float or complex.but in complex number magnitude is required
  '''
  '''
  d=float(input('Enter your desired number: '))
  d1=abs(d)
  print(f'The absolute value of {d}:   {d1}'+'\n')
  
  d= abs(19 + 21j) #trying to convert complex to abs()
  print(d)
  print('\n')
  x = 19.21e1/2 # exponential to abs()
  print(abs(x))
  print('\n')
  y = 0b1100 # binary to abs()
  print(abs(y))
  print('\n')
  z = 0o11 # octal to abs()
  print(abs(y))
  print('\n')
  w = 0xF # hexadecimal to abs()
  print(abs(w))
  print('\n')

  #   Round
  '''
  The round( gives the precise decimal value)
  '''
  print(round(3.955,1))
  #here 3.955 is the float value we want to round off, 1 is the place after or how many place we need to round off 
  #round(number, number of digits)
