fixed point is 100x more useful than float or double for the ranges of values games deal with... wonder why c/c++ dont have one built in

@tylerglaiel On@handmade_hero@cmuratori said that floating point is definitely faster in C. Interesting that you've found otherwise!1 reply 0 retweets 0 likes -

@JustASquid@handmade_hero@cmuratori note that this was only the case when optimization was turned on for me, and division was still 2x slo2 replies 0 retweets 0 likes -

@tylerglaiel@JustASquid@cmuratori Are you talking about 16-bit fixed point or 32-bit fixed point?1 reply 0 retweets 0 likes -

@tylerglaiel@JustASquid If 16-bit fixed point, sometimes that can be faster, yes. If 32-bit, I don't believe you :P1 reply 0 retweets 0 likes -

@tylerglaiel @JustASquid I feel like doubles should be much faster that 48.16 fixed point :/ Can you post the test?
