Simplest way to get 2 digits from an integer...

Hello All

I would like to find a simplest code to take the first n digits os a integer.
Here are two examples (not simple) to take the first 2 digits os the number a:

1)
a = 1234;
ToExpression@StringTake[ToString[a], 2]
12

2)
a = 1234;
FromDigits@Take[IntegerDigits[a],2]
12
-------
In Excel, I just use Left(a,2)*1 (multiply by 1 to get a number,
instead of text)
There is one simplest way in Mathematica!?

thanks in advance
Rodrigo Murta
