how to create a new column with a formula under square root

[ari2495]

Hi. I need to create a new column which is the result of a calculation. Specifically i need the new column to be the square root of ((1-var1)/var2). How can I include square root in sas? this is the code i would use but i do not know how to include square root

data output_datase;
	set input_dataset;
	new_column = var1 * (1-var1) / conteggio_rapport;
	run;

the square root has to involve the whole formula. thanks for help

SAS has a SQRT() function.

new_column = sqrt(var1 * (1-var1) / conteggio_rapport);

Or you can just raise the value to the 0.5 power.

new_column = (var1 * (1-var1) / conteggio_rapport) ** 0.5 ;
