When using the str_locate expression, Aster R outputs 0 when no occurrence of the string is found, but native R outputs NA.

For numeric values, native R retains the exact numbers as they are entered. Aster R will remove leading zeros.

Aster R will print the value Inf even if a table has the string "Infinity". Native R will match the infinity value correctly and prints it as infinity.
