Hi, I have this text string aa = {Cp11 t -40.00 r 3.73.csv }, I want to extract the number 3.73, so i write:

rapp = StringTake[StringDrop[aa, -4], -4]

So I have as result {"3.73"}. But it's in a text format.


How to convert the rapp = {"3.73"} to number format, so that i can use 3.73 to calculate ?


I hope in your help!

thank you!

The function for this is called "ToExpression". It takes a string and converts it into an expression in the Wolfram Language:

ToExpression["3.77"] + 1
4.77
