hello,
Sorry, i have ever send this message, but i need really an answer to continue my
project.
I have some problems with float : i'd like to add and substract some =
floats, i use Code Warrior 6 and when i write a float function like =
"FplAdd", this one is written in higtlight and the compiler refuse it.
when i use what i found in the archives :
RectangleType theRect;
FlpCompDouble theCompFloat;
char theString[80];
float theFloat;
// Convert a string to a float
theCompFloat.fd =3D FlpAToF( "12345.678" );
theFloat = theCompFloat.d;
// Convert a float to a string
theCompFloat.d =1234.678;
FlpFToA( theCompFloat.fd, theString );
it runs ok.
this is my function :
static void Calcule_add (char chaine1[10], char chaine2[10])
{
float ch1, ch2, result;
FlpCompDouble theCompFloat, theCompFloat2, theCompFloat3;
char addition[10];
char* charPtr;
// Convert a string to a float
theCompFloat.fd = FlpAToF( chaine1 );
theCompFloat2.fd = FlpAToF( chaine2);
ch1 = theCompFloat.d;
ch2 = theCompFloat2.d;
result = (ch1 + ch2)*10;
theCompFloat3.d = result;
FlpFToA(theCompFloat3.fd, addition);
charPtr = StrChr(addition, '.');
FrmCustomAlert(DebugAlert, "test",addition, charPtr);
}
i tested it with these strings :
char cha1[10] = {'1','5','.','5','4','\0'};
char cha2[10] = {'4','.','8','5','\0'};
when i add these two floats, this result is given to me : 2.0389999e01
the result is correct, but i'd like to obtain another format, like =
"20.39".
how can i add or substract floats ?
thank you.
