Re: [Pharo-project] FloatArray inaccuracy

July 28, 2011


      If forgot to specify that I run this on Pharo 1.3 build #226 in Windows with
:

Smalltalk vmVersion ----> 'Croquet Closure Cog VM [CoInterpreter
VMMaker.oscog-eem.56]'

Hi
I found that FloatArray>>at:put: is inaccurate:
| floats |
floats := FloatArray new: 1.
floats at: 1 put: 11.22321.
floats at: 1 " ------------> 11.223210334777832 "
Do you know this issue?
This is the implementation of at:put::
at: index put: value
    <primitive: 'primitiveAtPut' module: 'FloatArrayPlugin'>
    value isFloat
        ifTrue:[self basicAt: index put: value asIEEE32BitWord]
        ifFalse:[self at: index put: value asFloat].
    ^value
Thanks in advance
Martin
