Thanks, It works now. Infact I had to use sed to insert one more back slash that is replace "\" by "\\" to make it look like set x = 0.314\\0.314.
Thanks oncee again.

Hai,
Can you please guide me, to compare the floating point numbers.
Eg.
If
then
echo "value1 is grater "
fi

Hi All,
I'm trying to extract some floating point numbers from within some HTML code like this:

Hi I'm not using Korn93 but want to use floating point variable.
Is there any solution to do that ?
thx for help.

Hi guys
I have problem with my simple calculator, author of my book wrote
One way I tried is to test if one the inpur number is grater than zero, and then substatct

I have the following code snippet in bash

It works well for most of the cases. However lets say diff is -0.17 and minm is -0.0017. In such a case the comparison seems to fail. Is the correct way to compare a mixture of positive and... (12 Replies)

DESCRIPTION
The functions Pt, Rect and Rpt construct geometrical data types from their components. These are implemented as macros.
Add returns the Point sum of its arguments: Pt(p.x+q.x, p.y+q.y). Sub returns the Point difference of its arguments: Pt(p.x-q.x, p.y-q.y).
Mul returns the Point Pt(p.x*a, p.y*a). Div returns the Point Pt(p.x/a, p.y/a).
Raddp returns the Rectangle Rect(add(r.min, p), add(r.max, p)); rsubp returns the Rectangle Rpt(sub(r.min, p), sub(r.max, p)). Rmul
returns the Rectangle Rpt(mul(r.min,a), mul(r.max,a)); Rdiv returns the Rectangle Rpt(div(r.min,a), div(r.max,a)).
Rshift returns the rectangle r with all coordinates either left-shifted or right-shifted by a, depending on whether a is positive or nega-
tive, respectively.
Inset returns the Rectangle Rect(r.min.x+n, r.min.y+n, r.max.x-n, r.max.y-n).
Rcanon returns a rectangle with the same extent as r, canonicalized so that min.x <= max.x, and min.y <= max.y.
Eqpt compares its argument Points and returns 0 if unequal, 1 if equal. Eqrect does the same for its argument Rectangles.
Ptinrect returns 1 if p is a point within r, and 0 otherwise.
Rectinrect returns 1 if all the pixels in r are also in s, and 0 otherwise.
RectXrect returns 1 if r and s share any point, and 0 otherwise.
Rectclip clips in place the Rectangle pointed to by rp so that it is completely contained within b. The return value is 1 if any part of
*rp is within b. Otherwise, the return value is 0 and *rp is unchanged.
The functions Dx and Dy give the width (x) and height (y) of a Rectangle. They are implemented as macros.
