Select a valid choice. 2.6 is not one of the available choices

I have a model with a field having choices in it as given below. I am messing with the DecimalField somehow. And i cannot pass values like 1.7 or 2.6. But it is accepting 1.0 and 2.0 . Please let me know what am I doing wrong.

class Trip(models.Model):

    ACE = 1.00
    Dosth = 1.70
    TEN = 2.00
    FORTEEN = 2.30
    SEVENTEEN = 2.60
    NINETEEN = 2.90
    TWENTY = 3.10
    TWENTYTWO = 3.10

    VEH_CHOICES = (
        (ACE, 'ACE'),
        (Dosth, 'Dosth'),
        (TEN, '10.5FT'),
        (FORTEEN, '14FT'),
        (SEVENTEEN, '17FT'),
        (NINETEEN, '19FT'),
        (TWENTY, '20FT'),
        (TWENTYTWO, '22FT'),
    )
    ftype = models.DecimalField(null = True, blank = True, verbose_name = "Vehicle Type", decimal_places = 2, max_digits = 5, choices = VEH_CHOICES)

You need to change field DecimalField to FloatField i give the new model with change 

class Trip(models.Model):

    ACE = 1.00
    Dosth = 1.7
    TEN = 2.00
    FORTEEN = 2.30
    SEVENTEEN = 2.60
    NINETEEN = 2.90
    TWENTY = 3.10
    TWENTYTWO = 3.10

    VEH_CHOICES = (
        (ACE, 'ACE'),
        (Dosth, 'Dosth'),
        (TEN, '10.5FT'),
        (FORTEEN, '14FT'),
        (SEVENTEEN, '17FT'),
        (NINETEEN, '19FT'),
        (TWENTY, '20FT'),
        (TWENTYTWO, '22FT'),
    )
    ftype = models.FloatField(null = True, blank = True, verbose_name = "Vehicle Type", choices = VEH_CHOICES)

    def __str__(self):
        return str(self.ftype)

see diff of DecimalField and FloatField

Update this code to your code see it work. if it's work perfect or not let me know
