Reducing the decimal points of numbers (3d coordinates) in a file; how to input data to e.g. Python
I have a file full of coordinates of the form:
The numbers don't always have the same number of decimal points. I need to reduce the decimal points of all the numbers (there are 128 rows of 3 numbers) to 2.
I have tried to do this using Python but keep encountering obstacles when trying to use simple scripts I've found online surrounding the conversion/interpretation of the file itself. I don't seem to be able to input the numbers in the file as floats, or list(s) thereof.
I don't really want someone to write something for me; I'd like to try to understand the principle behind what it is I need to do, as a beginner to the language. Any help would be greatly appreciated.

Hi there,
I'm having a problem trying to extract data from within a text file. I'm trying to extract this manually for a lack of better words.
I need any items that fall within latitude 36.5 to 39.5 and long -75.3 to -83.9

Hi guys. Can anyone tell me how to determine points between two coardinates. For example: Which type of command line gives me
50 points between (8, -5, 7) and (2, 6, 9) points
Thanks (5 Replies)
Dear all,
Given that the coordinates of 4 points such as c1(x1,y1), c2(x2,y2), c3(x3,y3), c4(x4,y4).
Does any body know how to use plain sql / plsql to determine coordinates of a point e.g. (x,y) is within 4 points above efficiently. The 4 points supposedly form a rectangle rectangular.

Hi All,
I would like to set decimal point to 16 in the following bash script but it has syntax error at }:
awk '{printf"%.16e", (a<500,a++,$1/(a*1.1212121212121229e-02))}' input.dat >output.datHow may I set it in the correct way please? Thank you very much! (6 Replies)
I have a very large file with millions of entries identified by @M. I am using the following script to "extract" entries based on specific strings/patterns:

then
file=$1
else
echo "Input_file passed as an argument $1 is NOT found."
exit;

ppmcolormask
ppmcolormask(1) General Commands Manual ppmcolormask(1)NAME
ppmcolormask - produce mask of areas of a certain color in a PPM file
SYNOPSIS
ppmcolormask color [ppmfile]
DESCRIPTION
Reads a PPM file as input. Produces a PBM (bitmap) file as output. The output file is the same dimensions as the input file and is black
in all places where the input file is the color color, and white everywhere else.
The output of ppmcolormask is useful as an alpha mask input to pnmcomp. Note that you can generate such an alpha mask automatically as you
convert to PNG format with pnmtopng(1). Use its -transparent option.
ppmfile is the input file. If you don't specify ppmfile, the input is from Standard Input.
The output goes to Standard Output.
You can specify color five ways:
o An X11-style color name (e.g. black).
o An X11-style hexadecimal specifier: rgb:r/g/b, where r g and b are each 1- to 4-digit hexadecimal numbers.
o An X11-style decimal specifier: rgbi:r/g/b, where r g and b are floating point numbers between 0 and 1.
o For backwards compatibility, an old-X11-style hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or #rrrrggggbbbb.
o For backwards compatibility, a triplet of numbers separated by commas: r,g,b, where r g and b are floating point numbers between 0
and 1. (This style was added before MIT came up with the similar rgbi style.)
