[英]Multiplying the decimals in the column
我只想将第二列乘以 27.211396132。 我用
awk '{$2=$2*27.211396132 ; print }' input file > output file
结果是错误的。 我希望答案像 5 -76308.842049 （第一行）。 请帮我。
输入文件
output文件
使用printf 看这里
printf
echo "5 -2804.297202496805723" | awk ' { $2 = $2*27.211396132 ; printf "%s %0.8f\n", $1, $2 } ' 5 -76308.84204900
