Uli,

Use ToExpression.

"Uoc:0.752"
ToExpression[StringDrop[%, 4]]
Head[%]

"Uoc:0.752"
0.752
Real

Hi there,
we import a data file and want to extract a number from a string like 
e.g. Uoc:0.752
Of course we can extract 0.752 with Stringtake but we need to calculate 
with this number. How can we make Mathematica to understand it as a real 
number??
Thank you for any kind of help,
Uli
