How can i get accurate resultsof mathematical calculations in objective-c? -


i have simple mathematical calculation. have 2 floats n1 , n2.when evaluate simple division on these floats cannot accurate result in calculator. here simple code

float n1=55; float n2=23;  float n=n1/n2;  nslog(@"%.15f",n);

i see on console . wanted precesion upto 15 digits after decimal hence .15f 

2.391304254531860

but when calculate same division of 2 floats in scientific calculator value follows. how can same value using code? 

2.391304347826087

am missing silly , obvious? of great use. tia

the double type should used instead of float if need higher accuracy in calculations. double uses more bits store values float.

Java, Hibernate, MySQL - store UTC date-time -
