hi
has anyone ever managed to get trigonometric functions like sin cos or atan
to work using only mathf.h / libmf.a included with prc-tools or the build-in
functions? (with help from john) i got sqrt to work but the trigonometrics
always give 0 (prc-tools2.1, random crap value with prc-tools2.0).
is there some kind of initialization needed?
i'm trying to do this from within a hack, just in case it matters...
i know about mathlib but i would like to do it this way.
every help apreciated,
thanks,
felix
this code always gives me 0 for v:
#define pi 3.14159
float v, t1;
t1=1;
v=atan(t1);
//v is 0 now but should be 0,78539816339744830961566084581988
v=(v*180)/pi; //v in grad
//v is still 0 but should be 45
#ifdef debug
StrIToA(outputstringarray,(Int16) t1);
StrIToA(outputstringarray2, (Int16)v);
StrCat(outputstringarray, ", ");
StrCat(outputstringarray, outputstringarray2);
//Char *StrCat (Char *dst, const Char *src)
screenshout(outputstringarray);
#endif
