# But if “0”\*7 is the ‘normal’ way of doing this, it’s OK with me.

in ruby in general, the shorter and simpler, the faster.

it might be worth profiling something like this:

# at start of code

lotsazeros = ‘0’ \* 1000

# various places in code

seven\_zeros = lotsazeros[0…6]  
three\_thousand\_and\_ten\_zeros = lotsazeros \* 3 + ‘0’ \* 10

no idea how this performs, just thought it’d be worth trying…
