I'm having some trouble with float array.
When i try to get the array sum with float numbers i get this error line 39: soma + 2.34 | bc: syntax error: invalid arithmetic operator (error token is ".34 | bc")
when i type int numbers it works great, i just don't know why.
Thx.
Your variable soma is not set initially, that will through some error, along with usage of bc as RudiC noticed.
Good morning,
I'm testing the use of ceilf:
/*Filename: str.c*/
#include <stdio.h>
#include <math.h>
int main (void)
{
float ceilf(float x);
int dev=3, result=0;
float tmp = 3.444f;
printf("Result: %f\n",ceilf(tmp));
return 0;

Hi Everyone,
($total+=$_) for @record;
assume @record=(1,2,3), so the result is 6.

i tried " ($total+=$) for @record ", cannot, please advice.

cairo_clip_rectangle_list
CAIRO_CLIP_RECTANGLE_LIST(3) 1 CAIRO_CLIP_RECTANGLE_LIST(3)CairoContext::clipRectangleList - Retrieves the current clip as a list of rectangles
Object oriented style (method):
SYNOPSIS
public array CairoContext::clipRectangleList (void )
DESCRIPTION
Procedural style:
array cairo_clip_rectangle_list (CairoContext $context)
Returns a list-type array with the current clip region as a list of rectangles in user coordinates
PARAMETERS
o $context
- A valid CairoContext object created with CairoContext::__construct or cairo_create(3)RETURN VALUES
An array of user-space represented rectangles for the current clip
(The status in the list may be CAIRO_STATUS_CLIP_NOT_REPRESENTABLE to indicate that the clip region cannot be represented as a list of
user-space rectangles. The status may have other values to indicate other errors.)
EXAMPLES
Example #1
Object oriented style
<?php
$surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);
$context = new CairoContext($surface);
var_dump($context->clipRectangleList());
?>
The above example will output something similar to:
array(1) {
[0]=>
array(4) {
["x"]=>
float(0)
["y"]=>
float(0)
["width"]=>
float(50)
["height"]=>
float(50)
}
}
Example #2
Procedural style
<?php
$surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);
$context = cairo_create($surface);
var_dump(cairo_clip_rectangle_list($context));
?>
The above example will output something similar to:
array(1) {
[0]=>
array(4) {
["x"]=>
float(0)
["y"]=>
float(0)
["width"]=>
float(50)
["height"]=>
float(50)
}
}
