Description

normally distributed random number with mean=0 and sd=1, nSeed > 0 to set random seed (returns 0)

Syntax

double grnd( int nSeed = 0 )

Parameters

nSeed
(optional) pass any nonzero value to set the seed for random number generation, or 0 to use the current seed.

Return

A normally distributed random number.

Examples

EX1

// The example displays 10 normally distributes random numbers with mean=0 and
// standard deviation = 1.
void    grnd_ex1()
{
for (int ii = 0; ii < 10; ii++)
{
double    rr = grnd();
out_double("value = ", rr);
}
}
