round14 |
Function (ROM Call 0x175*) |
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.
