Function is working properly.
Values lower than 123.5 are rounded down to 123.000
Values higher than 123.5 are rounded around 124.000

If you want to round up all worth larger than (for example) 123.000 into 124.000, utilize MathFix(x 0.49999999)

Good job,thanks

Experienced an issue when attempting to compile Sessions.mq4 (https://www.nigeriaforextrading.com/...a-capable.html)
its concerning the mqh function DayNumber, I get:'(' - function definition unexpected
(experts/include/ -- extensible functions.mqh (6, 14) )

the terminal employed is r482; and I cant see the solution to fix it.

Compiles for me, I followed the instructions, no problems.

Hi,

just a little feedback nothing really important. Could not PM you so that I post it here

1.
On Your: Shellsort functions you appear to have left over a factor k that's never utilized.

2.
The ShellsortIntegerArray() function Appears to be considerably slower (approximately 10 times or so) compared to the MT4 ArraySort() on an Integer Array
for the MT4 function: ArraySort http://docs.mql4.com/array/ArraySort

Hi Hanover,

Thanks for sharing your Handy utility works. I would like to save time in coding my own custom indicator by using your handy functions.
Please give me some specific directions about the best way best to put your library works into work.
For example, in purpose PlotText I browse:
PlotText (objname, delete, window, time1, price1, text, color, size, font, angle, backg, vis);
I do not understand delete is what for.
Thank you for your help.

fareastol-
delete is of type bool. Look at the role to learn what each is.

Inserted Code // ------------------------------------------------------------------ int PlotText(string name, bool del=false, int win=0, datetime dt1=0, double prc1=0, string text=, colour clr=0, int size=0, string font=Arial, double angle=0, bool bg=false, int vis=0) // ------------------------------------------------------------------ if (StringLen(name)lt;1

Thanks a lot, Cyber1. Your instruction is quite clear.
Big pips to you!
