# Math routines

log2mod ( n -- mod n )
  Return the logarithm of n to the base 2 as well as the modulo of that
  operation. Example: $103 log2 yields n=8 mod=3

log2 ( n -- n )
  Same as log2mod, but without the modulo.

pow2 ( n -- n )
  Return 2 to the power of n.

isqrt ( n -- n )
  Return the integer square root of n. Example: 27 isqrt == 5
