real(dp) function	ran_ugaussian2 ()
	Computes a Gaussian random variate, with mean zero and standard deviation sigma=1.

real(dp) function	ran_gaussian2 (loc, scale)
	ran_gaussian computes a Gaussian random variate, with mean zero and standard deviation sigma

Detailed Description

Functions returning a variate x with normal probability.

Valid uses:

USE numfor, only rng_normal
x = rng_normal2()
x = rng_normal2(scale)
x = rng_normal2(loc, scale)

This version is faster than rng_normal() but is not thread-safe

Computes a Gaussian random variate, with mean zero and standard deviation sigma=1.

Note

This version caches the last unused value. It should be faster but will have problems in multi-threaded programs

Returns

Random number
