Hi guys,
i,m new here and very new in PIC programming...

i,m developing a project that calculate currency.
for example: i want to add 10cent,20cent, and 50 cent..

but i just know how to display decimal value only and kinda stuck with float value...
can anyone give me guide or example for this kind of code??

i'm using PIC 16F877A with HITECH C compiler.

thanx in advance..

sorry for my bad english..

I never use float number. If I want use decimal number, I store in integer. Eg, 1.23 saved as 123.
When display
lcd_number(no/100,DEC,1);
lcd_string(".");
lcd_number(no%100,DEC,2);

it depends on how many decimal u wan to display. below shows simple conversion for display
for example if u wan to display 111.222

u eliminate the decimal point 1st by converting it to integer

float fnumber=111.222;
int inumber;
inumber= (int) (fnumber);

then for decimal points, multiply the left over after subtract the float number from the int number with the 10 power the number of decimal point
float decimal;
decimal=fnumber-inumber;
decimal=decimal*1000; // for 3 decimal point

int dec_point;

dec_point= int (decimal );

so after this u can display the floating point number by printing both the value with a decimal point at middle of both

printnum(inumber);
printchar('.');
printnumber(dec_point);





or simple way, find a library to print it.

PROBLEM SOLVED!!

thanks guys!..i appreciate it...
it really helped me a lot..
