Hi all,
i have a string like this:

List(coeffs,2.6911587353182782e11*pow(g,1/2) -
9.7637089664852677e8*pow(g,0.625) +
1.7711703797165706e6*pow(g,0.75) - 1882.1107192280536*pow(g,0.875)
+
1.*g,-2.1529103878556243e12*pow(g,1/2) +
5.8581802093492619e9*pow(g,0.625) -
7.0846268915887993e6*pow(g,0.75) + 3764.1924139800627*pow(g,
0.875));

I would like to add double quotes around the constants, for subsequent
processing, to have:

List(coeffs,"2.6911587353182782e11"*pow(g,1/2) -
"9.7637089664852677e8"*pow(g,0.625) +
"1.7711703797165706e6"*pow(g,0.75) - "1882.1107192280536"*pow(g,
0.875) +
"1."*g,-"2.1529103878556243e12"*pow(g,1/2) +
"5.8581802093492619e9"*pow(g,0.625) -
"7.0846268915887993e6"*pow(g,0.75) + "3764.1924139800627"*pow(g,
0.875));

I tried to match the constants with regular expressions but i failed.

Can someone suggest me the way to do this with awk?

Please help me.

Thanks in advance.

Do you want 0.625 quoted?

0=2E875? And so on

Use this

{ gsub(/[0-9]+\.([0-9]+(e[0-9]+)?)?/, "\"&\""); print }

to quote any fractional number.
If there is more to it, be more specific.
