You can try this code I wrote 25 years ago and converted just now to SAS that works still with any base from 2 to 36 with decimals to four positions rounded.

%LET SIG = 4; %LET BASE = 36; %LET DIGITS = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';

DATA _NULL_;

LENGTH RESULT $ 20; INPUT @1 VALUE;

RESULT = ''; X = ABS(VALUE);

DP = MAX(INT(LOG(X)/LOG(&BASE)),0); DO I = DP TO 0 BY -1; DIGIT = INT(X / &BASE ** I); X = X - DIGIT * &BASE ** I; RESULT = TRIM(RESULT) || SUBSTR(&DIGITS, DIGIT+1, 1); END;

IF X > 0 THEN DO; RESULT = TRIM(RESULT) || '.'; DO I=-1 BY -1 UNTIL (X=0 OR I=(-&SIG-1)); DIGIT = INT(X / &BASE ** I); X = X - DIGIT * &BASE ** I; RESULT = TRIM(RESULT) || SUBSTR(&DIGITS,DIGIT+1,1); END;

IF I=(-&SIG-1) THEN DO; RESULT = SUBSTR(RESULT,1,LENGTH(TRIM(RESULT))-1); DIGIT = INDEX(&DIGITS,SUBSTR(TRIM(RESULT), LENGTH(TRIM(RESULT)),1))-1; DO WHILE (DIGIT = 0); RESULT = SUBSTR(RESULT,1,LENGTH(TRIM(RESULT))-1); DIGIT = INDEX(&DIGITS,SUBSTR(TRIM(RESULT), LENGTH(TRIM(RESULT)),1))-1; END; END;

result = compress(result); IF I=(-&SIG-1) AND DIGIT > &BASE / 2 THEN DO; LAST = 0; DO UNTIL (LAST); DIGIT = INDEX(&DIGITS,SUBSTR(TRIM(RESULT), LENGTH(TRIM(RESULT)),1))-1; DIGIT = MOD(DIGIT+1,&BASE); RESULT = SUBSTR(RESULT,1,LENGTH(TRIM(RESULT))-1); IF DIGIT > 0 THEN DO; LAST = 1; RESULT = TRIM(RESULT)||SUBSTR(&DIGITS,DIGIT+1,1); END; IF SUBSTR(TRIM(RESULT),LENGTH(TRIM(RESULT)),1) = '.' THEN DO; RESULT = SUBSTR(RESULT,1,LENGTH(TRIM(RESULT))-1); C = 1; DO I=LENGTH(TRIM(RESULT)) TO 1 BY -1; DIGIT = INDEX(&DIGITS,SUBSTR(RESULT,I,1))-1; DIGIT = MOD(DIGIT+C,&BASE); SUBSTR(RESULT,I,1) = SUBSTR(&DIGITS,DIGIT+1,1 IF DIGIT THEN C = 0; END; IF C THEN RESULT = '1'||COMPRESS(RESULT); LAST = 1; END; END; END; END;

IF VALUE < 0 THEN RESULT = '-'||COMPRESS(RESULT);

PUT @5 VALUE= @25 RESULT=;

CARDS; 3968 75 10 -37.40362 0.000643 16.277778 46655.9999996 ; RUN;
