scanf and float value
why is it that if i put %.2f in the scanf line i get garbage in the conversion ? i have a %.2f in the printf line below to get a 2 decimal value so i thought it has to be the same for the scanf. with %f it works fine.
// Convert Inches to Millimeters
{
float inch;
printf("Enter inch value: ");
scanf("%f", &inch);
printf("\nThat is equal to %.2f millimeters",inch*25.4);
return 0;
}
thanx
its alive... its ALIVE... ITS...AL...IIIVE !!!!!!!!!
Why are you allowing decimal input for inches? They're entering "2.345346 inches"? I would just use an integer.
Quzah.
Hope is the first step on the road to disappointment.
what if someone decides to enter 2.25 inches ?
will it be ok to use int ? will int ignore after the decimal point ?
i wil try it out to see. however, to answer your question, yes. the inch values will be up to 4 decimal. and the conversion to mm has to stay within 2 decimal accuracy.
is there a way to not print unnecacary 0's ? eg for 2.10 print 2.1 instead ? but retain 2 decimal accuracy for when needed ?
