How to separate the elemen of float?cause I want to take 2 number behind the .

Answer 1

Do you really need to cut it off? Or is it only for output?

double n = 6.6754335
printf("%.2lf", n);

output: 6.67

Answer 2

I would turn it into a string and manipulate from there?

Tested in Java - pretty sure it can be shorter and the logic is a bit cumbersome but maybe it can help you build your own version

float myFloat = 55.25F;

String floatVal = String.valueOf(myFloat);

int firstNum = floatVal.length() - 2;
int secondNum = floatVal.length() - 1;

System.out.print( floatVal.charAt(firstNum ) );
System.out.print( floatVal.charAt(secondNum ) );

Answer 3

I want to separate it into 1 individual number

Answer 4

float myfloat = 34.54f;
float post_DP = myfloat-(int)myfloat;
printf("%.2f", post_DP);
//or this...
printf("%.0f", post_DP*100);

Answer 5

ahh...separate (individual numbers) then:-
float myfloat = 34.54f;
int myfirstInt = (int)(myfloat*10)%10;
int mysecondInt = (int)(myfloat*100)%10;

printf("%d and %d", myfirstInt, mysecondInt);
