#15646: ghci takes super long time to find the type of large fractional number -------------------------------------+------------------------------------- Reporter: Johannkokos | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: GHCi | Version: 8.4.3 Resolution: | Keywords: type Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Johannkokos): The problem seems to be specific to scientific notation literals. On GHCi, Both {{{ 10^1000000 :: Double }}} and {{{ :t 10^1000000 :: Double }}} terminate near-instantly, while there is a noticeable delay with {{{ 1e1000000 :: Double }}} and {{{ :t 1e1000000 :: Double }}} .
