Hello

I have a number that, after leaving it in two decimal places with Round, does it well, but I am interested in leaving it in two decimal places without rounding.

Example:
2000.5354 (Round, -2) =2000.54
I want: 2000.5354 = 2000.53

Ask:
Does Gambas have a way to do it, without doing:

2000 (Fixed)
0.5354 (Frac)

And then trim it with string functions.

My solution would be: -

Very good, happy my eyes. "I hope it is well translated"

Thank you so much.

Greetings.

Code (gambas)

1. Print Int(2000.5354 * 100) / 100

There, you can also use the CInt() function.

If you want, you can also decide how many decimals to leave:

 Thanks, vuott, I'm glad to greet you.

Your proposal seemed very interesting to me since I can even determine the number of decimal places.

But I was left with honey in my mouth when you said the CInt conversion function without seeing your intention in the explanation or a code to understand you.

Simply…

or perhaps, to generalize

As usual, keep in mind Floating Point Mis-arithmetic!

This question is like Christmas. Full of forum stars

Now only BruceSteers is missing and this is Christmas in full.

Well thank you, gentlemen, I found it very interesting.

Haha , I have my uses   but I also know when to sit back and let those who know better have a say

I'd have just used string functions for something like this

I found this here: -

The difference between Int() and CInt() is:

Int() may return a Float value, CInt() is limited to 32 bit Integer.
Int() rounds to the next lower value. i.e. -4.6 to -5, while CInt rounds towards 0 i.e. -4.6 to -4


How does Int return a Float value?

I was done the same, was used string functions. That's why you ask the question.

On the other hand, Cogier you have managed with your last reflection to make my neurons a mess. But what question are you asking?

Sorry, I was not trying to fry your brain!

The purpose of Int is to create an Integer. So how can it return a Float?

Uhmmm… perhaps the question should be put in Gambas "Mailing List".

Int() can return a float value because…
Dim fNum as Float
fNum=Int(1.234)
Print fNum

1.0000

whereas

Dim fNum as Float
fNum=CInt(1.234)
Print fNum

!@OUrg Expected float got Integer

What is misrepresented here is f(x) returns a value that can be interpreted as a variable on the left hand side of the assignment and therefor be a valid assignment.
Think this way, if fNum was a Float[] then you would not expect fNum=Int(1.234) to work but fnum=[Int(1.234)] should. There are many similar cases where the assignment could be misunderstood as being a nonnegotiable translation but in fact they are. One of the beauties of this is that an Object can in fact be anything so if the assignee is an object then the assignment can work.

I can't get my head around this. My brain hurts now. :?
