Question

I have a string which holds a decimal value in it and I need to convert that string into a floating point variable. So an example of the string I have is ‘5.45’ and I want a floating point equivalent so I can add .1 to it. I have searched around the internet, but I only see how to convert a string to an integer.

Answer 1

You don’t need to convert it at all:

% perl -e 'print '5.45' + 0.1;' 5.55
