[Gambas-user] Best ways to format float values

[Gianluigi]

The street indicated by Tobias should be the safest, right?

I try to attach Adrien's link instead of the code:

>> Rounding depends on what rounding you want.
>> Most people think of 5/4 rounding.
>> I prefer to round manually 5/4... 5 up, 4 down.

>> Dim n as Float = 26.660166666666
>>
>> n = n * 100.  'n = 2666.0166666666   ' 2 decimal points rounding
>> n = n + 0.5   'n = 2666.5166666666 <(516)%20666-6666>   ' 5/4 rounding*
>> n = CLong(n)  'n = 2666
>> n = n / 100.  'n = 26.66
>>
>>
>> *If you wish to round down, do not add 0.5.  (add 0.0)
>> *If you wish to round up, add 0.999999999
>>
>> If you wish to do 3 digits, then *1000 and /1000.
>> This works for any type of rounding scheme and any reasonable number of
>> digits.
