Please take a look to the following piece of code:

+ Code Snippet

// Project: Floats
// Created: 2016-10-02

// set window properties
SetWindowTitle( "Floats" )
SetWindowSize( 1024, 768, 0 )

// set display properties
SetVirtualResolution( 1024, 768 )
SetOrientationAllowed( 1, 1, 1, 1 )

array as integer[]
col_count as integer

array.length = 7
col_count = 3

do
	row_count# = Ceil((array.length + 1) / col_count)
	Print(row_count#)
    Sync()
loop

The output is 2.0 but it should be 3.0
Since the Ceil function accepts a floating point number, as an argument, then both of the operands of the calculation should be treated as floating point numbers (or at least the result of the calculation)

Hi George++
you need to have at least one of the dividing/divided numbers as a float for it to work it would appear.

I updated your example (changed 1 to 1.0) and it works.

// Project: Floats
// Created: 2016-10-02
 
// set window properties
SetWindowTitle( "Floats" )
SetWindowSize( 1024, 768, 0 )
 
// set display properties
SetVirtualResolution( 1024, 768 )
SetOrientationAllowed( 1, 1, 1, 1 )
 
array as integer[]
col_count as integer
 
array.length = 7
col_count = 3
 
do
    row_count# = Ceil((array.length + 1.0) / col_count)
    Print(row_count#)
    Sync()
loop

cheers

It\'s late, I\'m tired, out of coffee and now I\'m wet.

Hi Harlequin,
Thank you for your response and for the tip. I know how to face this issue.
I would like to see if the TGC, agrees that this is a compiler issue or not. If the TGC agrees then this could be treated as a future update.
As far as I know, any C++ compiler does not behaves like the AGK

If both sides of a division are integers then the result will be an integer, this is the same as C++

instead of automatically convert int to float or float to int i like to have it optional and convert via a command.
example:
local a as float
local b as integer
local c as integer
a = Float(b+c)
or
b=c+Int(a)
