returns True if x and y are equal or almost equal upto defined
accurracy (ulps).It is recommended to use this function instead of
equality check (==) as itleads to more reliable comparisons and less
headache caused by IEEE floating pointacurracy issues.
>
> Parameters:x, y - the numbers or arrays to be compared,Ulps stands
for "units in last place" and represents maximum relative error of the
comparison. Since 32 bit IEEE floating point numbers have accurracy of
7 significant digits, 1 unit in last place(ulp) represents relative
error of 0.00001 %. The default value of ulps parameter is 5 which
gives roughtly 0.00005% "comparison sensitivity".

> Values returned are equal to those visible in the status bar, and
these functions require status bar to be visible. Returned values
represent cursor position at the formula execution time (or few
milliseconds before it) and accurracy is subject to pixel resolution
of the screen (first cursor position is read in screen pixels
(integer) and then converted to actual value therefore for example
when screen resolution is 1024x768 maximum obtainable resolution in X
direction is 0.1% and in Y direction 0.13%), also X values are snap to
datetime of nearest data bar.

indicator/interpretation code.

> Using them in AA window may yield random
values.GetCursorXPosition() function returns X position in DateTime
format (the same as used by DateTime() function).You can convert it to
string using DateTimeToStr() function.GetCursorYPosition() returns Y
position (as displayed in Y axis of the chart).

> Note: N-volume bars are somewhat weird (compression of data to
N-volume bar may actually deliver MORE output bars - for example if
one tick is 1000 shares and you have specified 100V bars then single
tick will be expanded to TEN 100V bars - ten times original size)
> TimeFrame functions are protected against array overrun and will
not decompress beyond original array size (you will get an "Error 47.
N-volume bar compressed data longer than base time frame").
> Also switching main time frame to some weird N-volume bar value
will result in limiting the output to maximum twice original data
size(without error message).
> You should keep that in mind and avoid using too small N-volume
bar intervals that could lead to such condition.
> Also due to the nature of N-volume bars the only TimeFrameSet()
function will yield correct N-volume bar values, TimeFrameGetPrice()
may give slightly distorted results.
> It is also possible to use n-volume bars in TimeFrame functions
without calling TimeFrameMode() - it is then necessary to specify
n-volume bars as negative number offset by -1000000 (minus one million):
>
> TimeFrameSet( -1000000 - 2000 );
>
> // gives 2000V barsSimilarly formatted negative numbers will be
reported by Interval() function when n-volume bars are selected.

than 10x10 pixels and can not be bigger than entire screen dimensions.
