##### pow function not working properly
« on: March 02, 2016, 08:07:06 am »
Hi guys!
I discovered recently that the pow function isn't working as it should. For example: pow(10,2) is 99, whereas it should be 100. Pow(100,1) is also 99. I could go on and on giving examples, but I think you understand my point. Could you fix it please? I'm using version 13.12

1.  This isn't a Codeblocks problem.
2.  pow() returns a floating point value, so you're probably seeing a rounding error converting it to integer.  Find or build a replacement function that uses integer math, or just simply round the result up to the nearest integer like this:
Code: [Select]
`int x = pow(10,2) + 0.5;`
