Random numbers

Random numbers
You are encouraged to solve this task according to the task description, using any language you may know.

The goal of this task is to generate a 1000-element array (vector, list, whatever it's called in your language) filled with normally distributed random numbers with a mean of 1.0 and a standard deviation of 0.5

Java

Double[] list = new Double[1000];
for(int i = 0;i<list.length;i++) {
  Double n;
  while((n=Math.random()) > 0.5);  // Continue to randomize until the value is or below 0.5.
  list[i] = 1 + n;
}

IDL

result = 1.0 + 0.5*randomn(seed,1000)

Tcl

proc nrand {} {return [expr sqrt(-2*log(rand()))*cos(4*acos(0)*rand())]}
for {set i 0} {$i < 1000} {incr i} {lappend result [expr 1+.5*nrand()]}
