import math
maxValue = 12345678
a = maxValue/4.0 # Python 2.x requires either numerator/denominator to be a float to return one
print "This is the value of a", a
print "This is the ceiling of the division", math.ceil(a) 

This is the value of a 3086419.5
This is the ceiling of the division 3086420.0

import math

maxValue = 12345678
a = maxValue / 4.0
print("This is the value of a: {}".format(a))
n = int(round(math.ceil(a), -4))
print("This is the ceiling of the division: {}".format(n))

Output:
This is the value of a: 3086419.5
This is the ceiling of the division: 3090000

def round(x,N):
    return ( (x+N/2) // N) * N

import math
maxValue = 123 # maximum value
a = maxValue/4.0 # Python 2.x requires either numerator/denominator to be a float to return one
integerPart = str(a).split('.')[0] # if "a" is a decimal this selects the integer part
numberDigits = len(integerPart) # length of integerPart

def upperRound(x,N):
    return ((x+N/2) // N) * N

print "Maximum value = {}".format(maxValue)
print "Maximum value/4 = {}".format(a)
print "length of integer part = {}".format(numberDigits)
print upperRound(a, 10-numberDigits)

Output:
Maximum value = 123
Maximum value/4 = 30.75
length of integer part = 2
32.0

Basically I want this script to be fully automated other than the maxValue being input by human, so for any maxValue/4, the output from upperRound should be bigger.

 print math.ceil(a)
