It is much much safer and clearer to use TRUE/FALSE than T/F. So

For the record, the array.apply code can be fixed as below, but then it is

Unfortunately for you, this email list is about R (not C), and while the
Posting Guide indicates that questions discussing how to interface with C
belong in R-devel, that is not a forum for learning C.
On the plus side, the data types and macros you are asking questions about are

The requirement for "random" is ill-specified because it omits mention of which
random distribution you want (I assumed normal distribution above).
The requirement for "decimal places" is ill-defined because floating point
numbers are internally represented with mant
