Not correct string number

[tigertv]

Bigint a("m");

The following code gives a loop.

Runnable example

"m" isnt a valid argument. What output do you expect?

Can either:

1. Throw
2. Cast to 0

I'm leaning mostly towards (1)

Exception, not a loop.

Throwing makes the most sense, or in the case that -fno-exceptions is on, then std::abort() and document that invalid input is simply not tolerated.
