Define LibPub days(m,d,y)=
Prgm
Local day, yt5,ye
yt5:=y*5
If  m=1 Then
ye:= 1
EndIf
If  m=2 Then
ye:=4
EndIf
If  m=3 Then
ye:=4
EndIf
If  m=4 Then
y:=0
EndIf
If  m=5 Then
y:=2
EndIf
If  m=6 Then
y:=5
EndIf
If  m=7 Then
ye:=0
EndIf
If  m=8 Then
ye:=3
EndIf
If  m=9 Then

EndIf
If  m=10 Then
ye:=6
EndIf
If  m=11 Then
ye:=4
EndIf
If  m=12 Then
ye:=6

day:=approx({intDiv[yt5,4]+ye+d}/7)
Disp day

This language is a variation of basic. It outputs a number eg. 20.57198 but the problem with input is that i only need the first number past the decimal. Questions on syntax and meaning will be answered. thank you.

Are you looking for a translation of this to C++, and then the C++ solution to obtaining the integer part of the number?

I do not understand your question. Do you need help with the language or as webJose said on the translation?

no, i am looking for how i would take the .5 from 20.57 in C++, then i should be able to translate it

#include <iostream>
using namespace std;
int main ()
{
       float MyFloat = 20.57 -  0.5;
       cout << MyFloat << endl;
       cout << "Press ENTER to end the program." << endl;
       cin.get ();
       return 0;
}

is this what you want?

If you need truncation of the decimal part:

1
2
3
4
 
float myFloat = 20.57;
cout << myFloat << endl;
int myInt = int(myFloat);
cout << myInt <<endl;

If I understood correctly.. OP just wants the first digit after the decimal point,

1
2
3
4
 
inline int frac_nth_digit(double num, int digit)
{
    return static_cast<int>( fmod(num * pow(10.0, digit), 10) );
}

cout << frac_nth_digit(20.57198, 1);

yes, i just want the first digit past the decimal
closed account (SEbXoG1T)
but is there a way you could translate that to basic?

20.57198 * 10 = 205.7198
205.7198 % 10 = 5.7198

The % (Modulo) operator returns the remainder of division in C.

nope, neither work
closed account (SEbXoG1T)
Wait, no never mind i added this

d1:=day*10
d2:=int(mod{d1,10})

Thank you all

The modulus is extremely inaccurate. need a more accurate method
