expdist
NAME
expdist - Pseudorandom number generator with exponential
distribution.
SYNOPSIS
double expdist()
DESCRIPTION
Expdist is a random number generator returning the exponen-
tial distribution e^(-x). Numbers are obtained through
calls to GFSR. Old states can be read using readGFSR(). New
states can be preserved using writeGFSR(). For more informa-
tion on preserving states, see gfsr(3).
FORTRAN COMPATIBILITY
Expdist may also be called from Fortran, as a function of
type DOUBLE PRECISION (i.e., REAL*8).
