How to get integer part of a float ?

[Flyingrock]

Hi,

After calculation in my programm I get a float number eg: 363.08954.

I wish keep only 363, I don't want to convert into a string, but get an integer, this integer will be use again in my programm to determine a pixel position.

Any idea ?

Look at the c math library there are functions in there that will give you both the fraction part as well as the Integer part or just do this

Code: Select all

volatile float kad=363.4567;
volatile unsigned int int_part;

int_part=(unsigned int)kad;

Hello there FlyingRock (<--- Nice name )

Why don't you just define the result variable as an integer instead of a float?

In case that doesn't work for you, then please follow the advice of (Diode Blade), a guy with a cool name like that couldn't possibly give a bad advice

Kindest Regards

Hi, diode_blade and MaGiK

Sorry to reply so late.

I didn't find function in math library to extract the integer part.
I tried what you have recommended and it's working.

Thank you for your help.
