writefln, writeln and the things of Tango are nice and cute and safe, but if I have to save 250 MB of numbers (or 1 GB of them, or even more) then performance is important, and those cute functions are 2-3-5 times slower than printf. This means printf can save me minutes of running time. So I use printf. But if I use printf in C and I write:int main() { float f = 1.2345; printf("%d\n", f); return 0; } The compiler says me: warning: format '%d' expects type 'int', but argument 2 has type 'double'
This is a non-standard extension to C.
While DMD compiles it silently. Better to quickly add such warning/error to D compilers too.
D's answer to printf and its problems is writefln.
