[racket] Math library ready for testing

2012/12/11 Jens Axel Søgaard <jensaxel at soegaard.net>:

I have just pushed an improvement for prime? on
small numbers.

Before:
>> (time (for/sum ([n (in-range 1000000)]
>>                 #:when (prime? n))
>>         n))
>>
>> ; cpu time: 8944 real time: 9079 gc time: 257
>> ; 37550402023

Now:
cpu time: 1511 real time: 1541 gc time: 87
37550402023
