Hello,
I have often found bash to be difficult when it comes to floating point numbers. I have data with rows of tab delimited floating point numbers. I need to find the smallest number in each row that is not 0.0. Numbers can be negative and they do not come in any particular order for a given... (9 Replies)

Hello Guys,
I have a floating point number 1.14475E+15 I want to convert this number in to full number (Integer or Big integer). I tried couple of functions it did not work. When I use INT=${FLOAT/.*} I am getting value as 1. I don't want a truncated value

Hi,
see the simple code below

what happens?how can i avoid it?

Hi all!
Hi all!
I am working with a problem to find the smallest floating point number that can be represented.
I am going in a loop ,stating with an initial value of 1.0 and then diving it by 10 each time thru the loop.
So the first time I am getting o.1 which I wanted.But from the next... (4 Replies)

NAME
gluPerspective - set up a perspective projection matrix
C SPECIFICATION
void gluPerspective( GLdouble fovy,
GLdouble aspect,
GLdouble zNear,
GLdouble zFar )
PARAMETERS
fovy Specifies the field of view angle, in degrees, in the y direction.
aspect Specifies the aspect ratio that determines the field of view in the x direction. The aspect ratio is the ratio of x (width) to y
(height).
zNear Specifies the distance from the viewer to the near clipping plane (always positive).
zFar Specifies the distance from the viewer to the far clipping plane (always positive).
DESCRIPTION
gluPerspective specifies a viewing frustum into the world coordinate system. In general, the aspect ratio in gluPerspective should match
the aspect ratio of the associated viewport. For example, aspect = 2.0 means the viewer's angle of view is twice as wide in x as it is in
y. If the viewport is twice as wide as it is tall, it displays the image without distortion.
The matrix generated by gluPerspective is multipled by the current matrix, just as if glMultMatrix were called with the generated matrix.
To load the perspective matrix onto the current matrix stack instead, precede the call to gluPerspective with a call to glLoadIdentity.
Given f defined as follows:
f = cotangent(fovy/2)
The generated matrix is
f
------------ 0 0 0
aspect
0 f 0 0
zFar+zNear 2*zFar*zNear
0 0 ---------- ------------
zNear-zFar zNear-zFar
0 0 -1 0
NOTES
Depth buffer precision is affected by the values specified for zNear and zFar. The greater the ratio of zFar to zNear is, the less effec-
tive the depth buffer will be at distinguishing between surfaces that are near each other. If
r = zFar/zNear
roughly log2(r) bits of depth buffer precision are lost. Because r approaches infinity as zNear approaches 0, zNear must never be set to
0.
