B4J Question [SOLVED] Numberformat

[jayel]

hello,

Why is this both 10?

Dim mdouble As Double = 10.5
Log (NumberFormat2(mdouble,2,0,0,False))

Dim mdouble As Double = 9.5
Log (NumberFormat2(mdouble,2,0,0,False))

I want the second one to be 9 !

Because it's using Round Half Even (Bankers Rounding) to round the numbers.

 

[jayel]

Ok.
Can I get it to be 9 with another function?

 

[jayel]

No it doesn't it returns 10

 

[keirS]

Sorry I cut and pasted the wrong bit of code which is why I deleted the message.

Dim abc As BigDecimal
abc.Initialize("9.5")
Log(abc.Round(1,abc.ROUND_HALF_DOWN))

 

[jayel]

hmmm, where did you get the bigdecimal?
My variable is a double

 

[keirS]

Does't matter.

    Dim mDouble As Double = 9.5
    Dim abc As BigDecimal
    abc.Initialize(mDouble)
    Log(abc.Round(1,abc.ROUND_DOWN))

Still works.

The BigDecimal is from the BigNumbers library
