The tests reveal that OpenBSD has these anomalies: exp(-Inf) -> NaN, exp(Inf) -> Inf, but exp(-MAXNORMAL) -> 0 and exp(MAXNORMAL) -> +Inf, as expected. Examination of the R-1.7.0/src/nmath/pweibull.c file shows that pweibull() calls pow(), log(), log1p(), and R_D_exp(), and the latter is defined in ./src/nmath/dpq.h as #define R_D_exp(x) (log_p ? (x) : exp(x)) /* exp(x) */ I...
