Numeric Literals

Numeric literals are used when numeric data values are stored in character strings. For conversion of numeric SQL data to a SQL_C_CHAR string, or conversion of numeric C data to a SQL_CHAR or SQL_VARCHAR string, numeric literal syntax is used to specify what is stored in the target. For conversion of a numeric stored as a SQL_C_CHAR string to numeric SQL data, or a numeric stored as a SQL_CHAR string to numeric C data, this syntax is used to validate what is stored in the source.

Numeric literals should conform to the syntax defined in Appendix C, “SQL Grammar.”
