Dear all!

Someone can give me a small help in translate the below math operations in netlinx?

void ConvertToFixed( DOUBLE val, U08 v[4] )
{
U32 fixed;
val = val>15.9?15.9:val;
val = val<-15.9?-15.9:val;
fixed = (U32)(((S32)floor(0.5+8388608.0*val)) & 0x0FFFFFFF);
}


many thanks !!

    It looks like you may have copied it wrong. v is passed in but never used. But nonetheless, other than the ternary operation which isn't supported in Netlinx, it should just about be the same if you change the types to Netlinx types. I can't guess what the function does with all those magic numbers. Looks like poorly thought out code to me.

    At the end I found the solution using first the min and max functions in netlinx and then the floor function that are in the math.axi file, very handy file....
