- program PR0331(input,output);
const D1=0.4;D2=0.5;D3=-0.4;D4=-0.5;
var T1,T2,T3,T4,R1,R2,R3,R4:integer;
begin
T1:=trunc(D1);T2:=trunc(D2);T3:=trunc(D3);T4:=trunc(D4);
R1:=round(D1);R2:=round(D2);R3:=round(D3);R4:=round(D4);
writeln('trunc(',D1:4:1,')=',T1:2,' trunc(',D2:4:1,')=',T2:2,' trunc(',-D1:4:1,')=',T3:2,' trunc(',-D2:4:1,')=',T4:2);
writeln('round(',D1:4:1,')=',R1:2,' round(',D2:4:1,')=',R2:2,' round(',-D1:4:1,')=',R3:2,' round(',-D2:4:1,')=',R4:2);
end.
にしたら、
trunc( 0.4)= 0 trunc( 0.5)= 0 trunc(-0.4)= 0 trunc(-0.5)= 0
round( 0.4)= 0 round( 0.5)= 0 round(-0.4)= 0 round(-0.5)= 0
ってなっちゃう…やっぱり全部ゼロだ…
