matlab string number formatting

Question

I want have a number

a = 0.0123

and I want to convert it to a string in XX.XX% format. How can I do this? The best I've got to is:

sprintf('%f%%',a*100)

this gets me

1.23000000%

How do I specify I want 2 numbers in the front of decimal and 2 in the back (i.e. 01.23% or if it was 0.123, then 12.30% )
