I've seen it used to indicate a repeating decimal, for example

0.123(4) means 0.123444444444...

But I've never seen that notation used in the way you indicated. What was the context?

well, I figured it out. It means there are 12 zeros after the decimal point. I found this number in the "zeros and weight factors table for HERMITE POLYNOMIAL".

We have scientific notation for that.
