It is: http://community.freepascal.org:10000/docs-html/rtl/math/setexceptionmask.html You can turn off floating point exceptions using this procedure. > Is it backwards compatibility? > >> Or you may take a look IEEE specification if it is necessary to create >> your >> own big float support for larger precision with fractals. > > It seems really weird that there is no such unit in the standard > freepascal distribution.
