Why don't you read it back into a float instead of a string?
fscanf(filePtr, "%f", &norme)
C can't do automatic type conversion to/from strings. You need to use
functions like strtod or sscanf when doing string->value conversions.
(the atoX faily mentioned by others is not standard C, but is available
on most UNIX and some other platforms)
