Issue in converting a integer value to string for below program

[Anu123]

Hi All,

Trying to convert the c=12345678912345.61 value to string by using put function but is not working as expected. 
It looks SAS is having limitations in converting big numbers.
Is it possible to convert integer values( more than 17 digits) to string ?

data _null_;
c=12345678912345.61;
b=put(c,best32.2);
put b;
run;

Output :-  12345678912345.6

Because of the way SAS (and other software that uses 64-bit technology, like Excel) stores numbers (see here), numbers beyond 16 decimal digits will not be handled correctly.

For statistical analysis, such precision is not needed anyway.

Thank you for your answer,

Can you please let me know how to handle amounts more than 16 digits than in SAS ?

You can use much larger numbers (be cause of the exponent) in calculations, but not with precision beyond the 16th digit.
