Hi Protectors Of YCP,
which is the easiest way to display a float with 3 digits after the decimal point and rounding to zero?
Piece of, er, cake. Attached.
After introducing the builtins trunc and pow it's really a pice of cake (even with variable number of digits): string r3(float a, integer n) { const float factor = pow(10.0, tofloat(n)); return tostring(trunc(a * factor) / factor, n); } ciao Arvin PS: You have to start adding builtins some day ;) -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org
