is there a utility class to store unlimited floating point number?

[derek.ldn]

'double' data type can only represent 1.79769e+308 by maximum on a 32
bit machine. Is there a utility class somewhere to store unlimited
floating point number?

Thanks,

Thats incorrect, the range of a double is roughly double that
(negative range).
2.2e–308 to 1.8e308
Do you realize what 1.8e308 is? One trillion is 1.0e12.

Maybe on your 32 bit machine. The standard remains largely silent about this
issue.

Not in the standard. There are, however, third party libraries. A google
search should help.

You mean the range is different in a 64-bit machine?
