    LK.EXT.FX_DAILY_TT.CNY.BUY.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CNY.BUY.D: value 24.8994 vs Data Library 24.0200. USD/BUY 180.08 here vs ~167.0 the day before and after). A single bad row in the source file.

  • Rounding10 Jan 2018

    Two agencies: 22.9 and 22.99, difference −0.09.

    LK.EXT.FX_DAILY_TT.CNY.BUY.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CNY.BUY.D: value 22.9000 vs Data Library 22.9900. File 22.9 vs Library 22.99, both sides' neighbouring days at 23.0-23.12 - a small, plausible one-off rounding-level difference (0.09), not a data error.

  • Rounding26 Apr 2018

    This series reads 24.25; the same figure from the other source reads 24.31. Compared with LK.EXT.FX_DAILY_TT.CNY.BUY.D.

Every currency differs from the Data Library by under 0.2 LKR on this date - the file records 4 decimal places (e.g. USD/BUY 155.5247) where the Library's copy has 2 (155.43); a precision/rounding difference between two CBSL publications of the same TT rate, not an error.

    CBSL's exchange rate lookup pages against the Data Library

    CBSL's exchange rate lookup and the Data Library disagree on 13-18 days per currency between 2010 and April 2018, by a few cents to a few rupees (USD sell 2011-02-28: 91.67 in the lookup, 111.67 in the library). Most look like slips on one side or the other; which side is right is not established for each day.
