Intended primarily for high accuracy C integration or integration of smooth functions. The maximum number of significant digits obtainable in ANS C is the smaller of 18 and the number of digits carried in C double precision arithmetic. C ERR - is a requested pseudorelative error tolerance. Usually, C smaller values of ERR yield more accuracy and require C more function evaluations. The estimated C error is solely for information to the user and should C not be used as a correction to the computed integral.
ANS is set to zero.
Removed unnecessary intrinsics. Prologue converted to Version 4.0 format. C C Compute refined estimates, estimate the error, etc.
