log package:base-prelude

log :: Floating a => a -> a
base-prelude BasePrelude
log1mexp :: Floating a => a -> a
base-prelude BasePrelude
log1mexp x computes log (1 - exp x), but provides more precise results if possible. Examples:
  • if x is a large negative number, log (1 - exp x) will be imprecise for the reasons given in log1p.
  • if exp x is close to 1, log (1 - exp x) will be imprecise for the reasons given in expm1.
log1p :: Floating a => a -> a
base-prelude BasePrelude
log1p x computes log (1 + x), but provides more precise results for small (absolute) values of x if possible.
log1pexp :: Floating a => a -> a
base-prelude BasePrelude
log1pexp x computes log (1 + exp x), but provides more precise results if possible. Examples:
  • if x is a large negative number, log (1 + exp x) will be imprecise for the reasons given in log1p.
  • if exp x is close to -1, log (1 + exp x) will be imprecise for the reasons given in expm1.
logBase :: Floating a => a -> a -> a
base-prelude BasePrelude
flushEventLog :: IO ()
base-prelude BasePrelude
Immediately flush the event log, if enabled.
