Hi, I want translate matlab code in sas.

Below the matlab code:

if isinf(delta_VaR),

    delta_VaR=.9*sign(delta_VaR)*VaR;

end

My problem is the function isinf.

What do I do?

SAS is only going to use 8 bytes to store numerics, so there will be a limit to what SAS can consider to be infinite.  Here is a sample program to illustrate an approach:

data _null_;

x = 1234567890123456789;

y = x + 1;

if x = y then put 'Match';

run;

The program writes "Match", because the values of x and y are too large to store exactly in 8 bytes.  So this might be one version of "infinite" in the SAS world:

if int(var) = int(var) + 1 then do;

Good luck.
