How can I cast a text element to float in animation-nodes?

I read some data from an external csv file into animation nodes, split the lines into individual parts (data columns) containing floating point numbers and want to use these floating point numbers in an object transformation.

However, the split lines are of type text, while the transformation expects float. How can I transform text to float? In the image the current value is 7.5 as can be seen in the debug node, I'd like to use this as input to the combine vector node.

In python this is easy enough >>float() so I tried to do this, using the script animation node, but could not figure out how to deal with input/output values within the script node.
