float round14 (float x);

Rounds the floating point number to 14 significant digits.

round14 returns the value of the floating point argument x rounded to 14 significant digits. Also, arguments whose absolute values are greater or equal than 10^8192 are rounded to POSITIVE_INF or NEGATIVE_INF, and arguments whose absolute values are smaller than 10^-8192 are rounded to POSITIVE_ZERO or NEGATIVE_ZERO. TIOS always does such rounding before storing a floating point value to a variable.
