is int(round(val)) safe?

#- It's much easier than that to get integer floating point numbers that
#- aren't correct. Consider:
#- 
#- >>> long(1e70)
#- 1000000000000000072531436381529235126158374409646521955518210
#- 1554790400L

You always can use Decimal:

>>> from decimal import *
>>> getcontext().prec = 80
>>> Decimal("1e70")
Decimal("1E+70")
>>> Decimal("1e70") + 1
Decimal("1000000000000000000000000000000000000000000000000000000000000000000
0001")
>>> long(Decimal("1e70"))
10000000000000000000000000000000000000000000000000000000000000000000000L
