Time as float?
« on: November 03, 2011, 11:29:32 am »
I was taught that when programming, Time is is typically stored using an integer that represents milliseconds. However, I see that SFML uses floats to represent Time.

Should all of my sub-times that get assigned by and then compared to ElapsedTime() be floats? If I have them as as integers, will SFML have to convert them, thus using more (though I'm sure only slightly) processor power?

Or was I simply taught wrong, and using floats is actually the norm?

Thanks!!

SFML 2.0 uses unsigned int.

You should not care for processor power which is needed to convert between float and (unsigned) int, it won't have a noticeable effect.

Since it's been mentioned, can anyone tell me why was time changed from float to integer milliseconds? If I ever wanted an integer, I could always round the value. Why is it rounded for me?
