Problems in Decimal Package

[nk28]

I am having a very strange problem which I am unable to figure out.

I wanted all my data to be printed in decimals and not in exponential terms.

So I am using decimal module.

print "\n GENUINE ACCEPTANCE RATE :\t ", GA/Decimal(users)

Now I have set the precision to 9 and when I try to run in the shell it gives me the correct value but during execution of this program for GA=2 and users = 180,000,000 it still provides me exp answer.

And that too it gives me only for this value . Can anybody explain why this is happening.....

Thanks a lot...

2/180 million probably has too many leading zeros to fit within the 9 precision limitation, or it is the series of infinitely repeating ones that is larger than 9 precision. Try 2/180,000 as an experiment to see if that works. Then check the .quantize member of the decimal class.

from decimal import *
getcontext()
Context(prec=9, rounding=ROUND_HALF_UP, 
        capitals=1, flags=[], traps=[Overflow, DivisionByZero,
        InvalidOperation])
x = Decimal(2)
y = Decimal(180000)
result1 = x/y
print result1
 
print Decimal(result1).quantize(Decimal('.00000001'))

Hey,

It seems you are right as now both the values that you gave print 1.11E-8 , even when I have set the precision to 28.

IS there any way I can get this to work in decimal way.

Thanks a lot....
