F# 1.9.1.9 available (currently MSI only): Includes overloaded numeric conversion functions and checked arithmetic

  • Article

Hi all,

I'm glad to announce the availability of F# 1.9.1.9. It's available for download from this link:

research.microsoft.com/research/downloads/details/c8d270ce-dc93-4b82-8125-2c57036520b3/details.aspx

This is in general a bug fix release over 1.9.1.8, with some exceptions

  • We've added two great new features:
    • Overloaded numeric conversion functions. The functions int, float, float32 etc. now overloaded conversion operators. For example, you can replace Int32.of_float and Int32.of_int64 and all similar operators that convert to int by just int (or int32, which is equivalent). Likewise for sbyte, byte, int16, uint16int32, uint32, int64, uint64, nativeint, unativeint, float, float32, single, double.
    • Checked arithmetic Open Microsoft.FSharp.Core.Operators.Checked to get checked arithmetic versions of +, -, * and the above conversion operators.
  • We've updated the FLinq sample The FLinq sample has been updated to use the technique outline in Don Syme's ML Workshop LINQ paper from 2006. More details to follow in blog entries.
  • We've moved to an MSI installer for this release. This is to fix numerous installation problems with the previous Zip based installer. We will be making a ZIP available for Mono users of the compiler in due course
  • The --quotation-data flag is now deprecated (it does nothing). Instead you must explicitly label any code for which you want the definition available at runtime as a quotation term with the [<ReflectedDefinition>] attribute.

Bugs fixed:

 895     "type" links broken on F# manual pages online
893        unicode lex bug 0x800 - 0x7ff
894        file hashes not being added to assembly resouce 
900     --quotation-data flag problems causing problems for many things in F# Interative from Visual Studio
903      catch and report exceptions on user threads without killing fsi
907      quotation API TopDefnData should use an Assembly value.
909      Add Seq.cache_all
910        Seq.filter is broken on 64-bit
911       Fast F# cannot be unset, and should be ignored anyway
898        Invisible error location information reported in Visual Studio
912       {} still gives tyref_of_stripped_typ
914     Pattern matching code causes NullReferenceException
913      Nested enums not showing up under intellisense, e.g. System.Environment.SpecialFolder
904        explicit instantiation of generic type not found
905     Intellisense failure for static method in generic collection class
918       Poor error when generic type given the wrong number of type arguments
916        Should not be printing to stderr on "fsi --exec"
915 Add updated LINQ sample
923  Add Array2.rebase
922    Use arity-based overloading for collection types Tagged.Set, Tagged.Map, Tagged.HashSet, Tagged.HashMultiMap
