What setting will impact atof() output

wenckey

I run atof("9.12") in my CIW, it will return 9.11999999999999

And I run virtuoso -nocdsinit, it will return 9.12

What will impact that?

    Hi,

    This setting controls the display precision:

    sstatus(fullPrecision t)

    you can test the setting using status(fullPrecision).  The documentation states this:

     If t, unformatted print functions (print, println, printlev) print floating point numbers in full precision (usually 16 digits); otherwise, the default is about 7 digits of precision.

    Best regards,

    Lawrence.

    sstatus(fullPrecision nil)
    atof("9.12")
    => 9.12

    You didn't state what fullPrecision is currently set to, but I expect that it was set to 't', so setting it to 'nil' should give you the above result.

    Regards,

    Lawrence.
