Line 1: == '''C#''' solution for '''Xiaolin Wu's line algorithm''' ? == Any guy can give me '''Xiaolin Wu's line algorithm'''s code in C#. Than you. Line 64 ⟶ 65: ::: Once you make all numbers non-negative, FLOOR and IPART are synonymous. It's only when using negative numbers that the issue (any difference) is raised. -- [[User:Gerard Schildberger\|Gerard Schildberger]] 16:51, 4 June 2012 (UTC) :::: Yes, but I made some of them negative for the algorithm (just translating them to positive when they were rendered). --[[User:Rdm\|Rdm]] 17:02, 4 June 2012 (UTC) ::: Concerning another issue: FPART. When handling negative coödinates, I was wondering if FPART is doing what it's supposed to do, but I couldn't find a good definition of FPART (with regarding to negative numbers) --- but I'm still rooting around the 'net. For non-negative numbers, the simple definition of FPART (even if wrong), still gives the correct answer. FPART of 6.78 is +0.78. But what about -8.91 ? Is the fractional part +0.91 or -0.91 ? --- I'm still trying to locate a good definition for it --- I hope the definition isn't tied (or restricted to) any particular computer language. Perhaps someone could find a complete/good definition of FPART in their appropriate language reference documentation. -- [[User:Gerard Schildberger\|Gerard Schildberger]] 16:46, 4 June 2012 (UTC)▼ Concerning another issue: '''FPART'''. ▲~~::: Concerning another issue: FPART.~~ When handling negative coödinates, I was wondering if FPART is doing what it's supposed to do, but I couldn't find a good definition of FPART (with regarding to negative numbers) --- but I'm still rooting around the 'net.
