[Bug 28422] scanf family of functions provides only 7 digits of precision for converting doubles and long doubles

This patch is obviously required to sustain the desired long double precision
for this calculation of the long double cur variable. Without the patch, the
calculation is of double precision instead which introduces additional
numerical noise into the results for cur and also the scanf family of
functions.
