(info "(calc) Integer Truncation") has
#v+
The ‘R’ (‘calc-round’) [‘round’ or ‘fround’] command rounds to the
nearest integer. When the fractional part is .5 exactly, this command
rounds away from zero. (All other rounding in the Calculator uses this
convention as well.) Thus ‘3.5 R’ produces 4 but ‘3.4 R’ produces 3;
‘_3.5 R’ produces -4.
#v-
and
#v+
Each of these functions, when written in algebraic formulas, allows a
second argument which specifies the number of digits after the decimal
point to keep. For example, ‘round(123.4567, 2)’ will produce the
answer 123.46, and ‘round(123.4567, -1)’ will produce 120 (i.e., the
cutoff is one digit to the _left_ of the decimal point). A second
argument of zero is equivalent to no second argument at all.
#v-
So I suggest the following:
| 3.25 | |
| 6.5 | |
#+TBLFM: $2=round($1*0.15,2);%.2f
