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)

Hi,
I' using bash and I would like to use "bc" to compute the ratio of of two numbers and assign the ratio to a variable.
The numbers are in a file, e.g.
196.304492
615.348986
Any idea how to do it?
N.B. I cannot change the file to have 196.304492 / 615.348986 as the file is produced by... (14 Replies)

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)

GLGETMATERIAL(3G) GLGETMATERIAL(3G)
NAME
glGetMaterialfv, glGetMaterialiv - return material parameters
C SPECIFICATION
void glGetMaterialfv( GLenum face,
GLenum pname,
GLfloat *params )
void glGetMaterialiv( GLenum face,
GLenum pname,
GLint *params )
PARAMETERS
face Specifies which of the two materials is being queried. GL_FRONT or GL_BACK are accepted, representing the front and back materi-
als, respectively.
pname Specifies the material parameter to return. GL_AMBIENT, GL_DIFFUSE, GL_SPECULAR, GL_EMISSION, GL_SHININESS, and GL_COLOR_INDEXES
are accepted.
params Returns the requested data.
DESCRIPTION
glGetMaterial returns in params the value or values of parameter pname of material face. Six parameters are defined:
GL_AMBIENT params returns four integer or floating-point values representing the ambient reflectance of the material. Integer
values, when requested, are linearly mapped from the internal floating-point representation such that 1.0 maps to the
most positive representable integer value, and -1.0 maps to the most negative representable integer value. If the
internal value is outside the range [-1, 1], the corresponding integer return value is undefined. The initial value
is (0.2, 0.2, 0.2, 1.0)
GL_DIFFUSE params returns four integer or floating-point values representing the diffuse reflectance of the material. Integer
values, when requested, are linearly mapped from the internal floating-point representation such that 1.0 maps to the
most positive representable integer value, and -1.0 maps to the most negative representable integer value. If the
internal value is outside the range [-1, 1], the corresponding integer return value is undefined. The initial value
is (0.8, 0.8, 0.8, 1.0).
GL_SPECULAR params returns four integer or floating-point values representing the specular reflectance of the material. Integer
values, when requested, are linearly mapped from the internal floating-point representation such that 1.0 maps to the
most positive representable integer value, and -1.0 maps to the most negative representable integer value. If the
internal value is outside the range [-1, 1], the corresponding integer return value is undefined. The initial value
is (0, 0, 0, 1).
GL_EMISSION params returns four integer or floating-point values representing the emitted light intensity of the material. Inte-
ger values, when requested, are linearly mapped from the internal floating-point representation such that 1.0 maps to
the most positive representable integer value, and -1.0 maps to the most negative representable integer value. If
the internal value is outside the range [-1, 1.0], the corresponding integer return value is undefined. The initial
value is (0, 0, 0, 1).
GL_SHININESS params returns one integer or floating-point value representing the specular exponent of the material. Integer val-
ues, when requested, are computed by rounding the internal floating-point value to the nearest integer value. The
initial value is 0.
GL_COLOR_INDEXES params returns three integer or floating-point values representing the ambient, diffuse, and specular indices of the
material. These indices are used only for color index lighting. (All the other parameters are used only for RGBA
lighting.) Integer values, when requested, are computed by rounding the internal floating-point values to the near-
est integer values.
NOTES
If an error is generated, no change is made to the contents of params.
ERRORS
GL_INVALID_ENUM is generated if face or pname is not an accepted value.
GL_INVALID_OPERATION is generated if glGetMaterial is executed between the execution of glBegin and the corresponding execution of glEnd.
