DERFC

 
Double precision complementary error function, = (2 / square root of pi) * the
integral from x to infinity of exp(-t**2)dt.
 
Classes  :  C8a .   Error functions, their inverses, integrals, including the
                  normal distribution function
            L5a1e . Error function, exponential and extreme value
                  distribution and density functions
 
Type     : Fortran subroutine in IMSLM library.
Access   : Proprietary. Many implementations available.

Implementation of DERFC from IMSLM on ITL

 
ITL:       Unix Workstation Network, National Institute of Standards and
           Technology (NIST), Gaithersburg, MD. Available to NIST staff.
 
Precision: Double. (Single: ERFC)
 
Access available only to NIST staff on internal Unix systems. They may access this
package provided the /itl tree is cross-mounted.
