Hi !
Is it possible to integrate an ATan2 function ?

And would you implement it in the next version ?

It willn't be done for the next version.

Just use ASM. The FPU already does ATAN.
I don't know the syntax required for PureBasic in-line ASM but I'm sure someone will show you how to make it work..

Code: Select all

fld y      ;Get y onto the FPU stack 
fld x      ;Get x onto the FPU stack  
fpatan     ;Get the ATAN(y/x), Put result in ST(1) then pop the stack  
fstp res   ;store the result in res and pop the stack

Shouldn't it be enough to do Atan(y/x)?

Yes, no needed more than the basic math functions, else PB would be full of it (Cosh(), Sinh(), Tanh(), Atan2(), ln(), etc.), and that should be too much ugly for a PURE language.

If PB 4 allow macros you can do all those functions in ASM (or get it from this forum) and save it in a good place for your programs.

EDIT: I'm dying to work with macros to build my own module sources.
BTW, ElChoni, are you Tailbite Expert? Shouldn't be better to write Tailbite author?

Sorry, but Atan2 is different than atan(y/x), because atan2 should include some checks.

why not adding it as keyword when its just only some asm lines? i dont need such a command yet but even blitz basic has inbuild Tan2 support... (looking forward...)

[Edit:]
same for Pi() , Sgn() , MOD, NOT, XOR
