rand_uni
This routine returns a number out of a pseudo-random uniform deviate (ie, its
probability distribution is uniform in the range ]0,1[).
Location in HEALPix directory tree:
src/f90/mod/rngmod.f90
FORMAT var=rand_uni(
rng_handle
)

rng_handle |
planck_rng |
INOUT |
structure of type planck_rng
containing on all information necessary to continue same
random sequence. |
| var |
DP |
OUT |
number belonging to a pseudo-random uniform deviate. |
EXAMPLE:
use healpix_types
use rngmod
type(planck_rng) :: rng_handle
real(dp) :: uni
call rand_init(rng_handle, 12345, 6789012)
uni = rand_uni(rng_handle)
initiates a random sequence with the pair of seeds (12345, 6789012), and
generates one number out of the uniform deviate.
