I am looking for a better way to match real numbers within a specified tolerance range. My current code is as follows:
where $5 and G[i] are real numbers e.g. "12.456" and "11.543". Right now the code prints out several numbers within the range of 1+ 12.456 and 1-12.456.
Is there a better way of accomplishing this? I would like to get the closest number without manually having to adjust the tolerance range of 1.
i would like to enter (user input) a bunch of numbers seperated by space:
10 15 20 25
and use awk to print out any lines in a file that have matching numbers
so output is:
22 44 66 55 (10) 77 (20)
(numbers 10 and 20 matched for example)
is this possible in awk . im using gawk for... (5 Replies)

Hi everyone,
I need to compare 2 big Floating/Real numbers in a script.
After the comparission it is showing worng values in my script.
echo "Enter value1"
read value1
echo "Enter value2"

gshhs_dp
GSHHS_DP(1gmt) Generic Mapping Tools GSHHS_DP(1gmt)NAME
gshhs_dp - Line reduction using the Douglas-Peucker algorithm
SYNOPSIS
gshhs_dp input.b tolerance output.b [-v]
DESCRIPTION
gshhs_dp reads the binary coastline (GSHHS) or political boundary or river (WDBII) files and and reduces the complexity of the line by
applying the Douglas-Peucker algorithm. It automatically handles byte-swabbing between different architectures.
input.b
GSHHS or WDBII binary data file as distributed with the GSHHS data supplement. Any of the 5 standard resolutions (full, high,
intermediate, low, crude) can be used.
tolerance
tolerance is maximum mismatch in km. The larger the value the more reduction will take place.
output.b
The reducted data set.
OPTIONS -v Reports progress and statistics while running.
EXAMPLES
To simplify the full GSHHS data set with a custom tolerance of 2 km, try
gshhs_dp gshhs_f.b 2 gshhs_2km.b
