Yes.

It is the way val is intended to work. Use http://www.freepascal.org/docs-html/rtl/sysutils/floattostr.html 
  instead if you want to make use of the locale settings (do not  
forget to use the "clocale" unit in your program if you are on a Unix  
platform to initialise the locale settings, or manually specify a  
TFormatSettings parameter to floattostr).
