I didn't recognize, that your expression doesn't work correctly,
1.) because the parentheses are not balanced

so it should read (I presume)
str(float(int((Variable_for_money)*100))/100)
but 2.) it doesn't round properly:
>>> Variable_for_money=15.239
>>> Variable_for_money
15.239000000000001
>>> str(float(int((Variable_for_money)*100))/100)
'15.23'
And this comes so:
>>> Variable_for_money*100
1523.9000000000001
>>> int(Variable_for_money*100)
1523
>>> float(int(Variable_for_money*100))
1523.0
>>> float(int(Variable_for_money*100))/100
15.23
>>> str(float(int(Variable_for_money*100))/100)
'15.23'
