Why does division result in zero instead of a decimal?

Question

Teaching myself C and finding that when I do an equation for a temp conversion it won\'t work unless I change the fraction to a decimal. ie,

tempC=(.555*(tempF

Answer 1

5/9 is an integer division not a floating point division. That's why you are getting wrong result.

Make 5 or 9 floating point variable and you will get correct answer.

Like 5.0/9 OR 5/9.0
