Question

Answer 1

+3 A:

You can simply divide by 100 and ceil the value.

What language are you using?

PHP example: $part = ceil($number/100);

Warning: this works if the division is floating point division, but not if it's integer division, e.g. in Java, `Math.ceil(234/100)` will return `2.0`, not `3.0`. Use `100.0` rather than `100` in languages where it makes a difference.

In Java you can do `Math.ceil(1.0*234/100)` to force it to use floating point.

The ceil() function was exactly what I was looking for. Thanks!

Indeed, once you're aware of the problem there are lots of solutions. But until you're aware, it can be confusing.

Answer 2

A:

Language is important here but usually you can either use a ceiling function, or cast the numbers as integers and add 1 to it like I have below for C++

int parts_per_hundred(int value) {

// value / 100 will give you an integer. 
// we subtract 1 from the value so multiples of 100 are part of their number not the next highest.
int result = ((value - 1) / 100 ) + 1;

return result;

}

parts_per_hundred(0) returns 1.
