How to convert float to long?

I have a 7 segment LED display routine that requires a long (16bits) data type.

I have to do some fancy calculations that require float. I know how to cast up to float but how do you "cast down"

I have tried the following...

float x=12.34
long y

both y=x and y=(long) x give y a value of 0 (zero)

Any ideas?

Thanks in Advance

What are you expecting "y" to be in your example?

An assignment operation should make y=12 (truncation). If it is coming back as zero there may be a compiler bug so I'll ask the 64 cent question, what version of compiler are you using?

I'm expecting y=12 and it's 0

Version is CCS v 3.112 (I think! - How do I verify)

Select 'Help' on the menu bar and then 'About'. This will tell you which version you have.

Using the PCM version - in looking at some of the files in the directory - it's 3.112

You probably don't want to hear this but I think it is a compiler bug.

Try being a little more specific with your variable declarations:
