Hello

Can anyone explain in words what this proc format is doing?

May show a practical example when we can use it?

proc format;
picture show (round)
0-high = 99.99
low - <0=099.99 (prefix='-')
;
run;

It is displaying a positive number (rounded off) as two digits (one or both of them could be a leading zero) before the decimal and two digits after the decimal. If the number is less than zero, there can be three digits, a minus sign and no leading zero.

proc format;
picture show (round)
0-high = 99.99
low - <0=099.99 (prefix='-')
;
run;
data example;
    x1=8.03;
    x2=8.037;
    x3=-1.90;
    format x1-x3 show.;
run;
