Here is an example of how to truncate a variable to a whole number:
var1=31.75 ;start with real number
varb1=vcvt(var1) ;convert to binary variable
var2=vcvt(varb1) ;convert back to decimal variable
var2=31.0 ;var2 is now 31.0
If you want to round this number instead of truncate,
add the following to the previous code
var3=var1-var2 ;subtract the truncated number
;from the original real number
;(to get just the decimal places)
if(var3>=0.5)
var1=var2+1 ;use an if statement to round
else ;up or round down
var1=var2
