round12 |
Function (ROM Call 0x174*) |
Rounds the floating point number to 12 significant digits.
round12 returns the value of the floating point argument x rounded
to 12 significant digits. TIOS sometimes does such rounding, for example when
TIOS updates coordinate values (xc, yc, etc.), during printing approximate
results, or when TIOS stores a value to system variables like xmin, xmax etc.
(strictly speaking, TIOS calls round12_err instead
of round12 in such cases).
