[C] How do I reduce the precision of a double? - Tilted Forum Project Discussion Community

Basically, I want to accept any number form, 1.2 14123.224324, 12414, .000512, And produce an answer after calculation, with only 2 places after the decimal, and everything before it. So if I was to scanf and get 123123.2255 And then do a printf, print back out 123123.22

Is this possible?

Damnit I'm an idiot. %.2lf haha. I was trying .2lf on the scanf and printf functions and it was screwing it all up. Didn't think of just doing it on the printf portion.
