How do you round down a number?

Blitz3D Forums/Blitz3D Beginners Area/How do you round down a number?

If I have a number 14.632 for example, how do I round it down to the nearest whole number, in this case 14 ?

I want the answer for anything above ie 14.001 - 14.999 so it will always be 14, same for 225 etc.

thanks

int(num) can be used for such a thing

Not true as INT( 14.999 ) will be 15.0 and floor() would be a pointless function.

How about

if a >14 and a <15 the a=14

????

Yes, floor() is what you want. Also, Int behaves in a bit of a weird way in blitz, so be careful! From the docs:

Int converts floating point numbers by rounding to the nearest integer.
NOTE: This is not the traditional meaning of Int in Basic.

What about numbers exactly halfway between integers?
The rounding is to the nearest even integer:

Int( 2.5 ) ... produces 2
Int( 3.5 ) ... produces 4
