# Numeric Literal Syntax
The following syntax is used for numeric literals in ODBC:  
  
 *numeric-literal* ::= *signed-numeric-literal | unsigned-numeric-literal*  
  
 *signed-numeric-literal* ::= [*sign*] *unsigned-numeric-literal*  
  
 *unsigned-numeric-literal* ::= *exact-numeric-literal | approximate-numeric-literal*  
  
 *exact-numeric-literal* ::= *unsigned-integer* [*period*[*unsigned-integer*]] *|period unsigned-integer*  
  
 *sign* ::= *plus-sign | minus-sign*  
  
 *approximate-numeric-literal* ::= *mantissa E exponent*  
  
 *mantissa* ::= *exact-numeric-literal*  
  
 *exponent* ::= *signed-integer*  
  
 *signed-integer* ::= [*sign*] *unsigned-integer*  
  
 *unsigned-integer* ::= *digit...*  
  
 *plus-sign* ::= *+*  
  
 *minus-sign* ::= -  
  
 *digit* ::= 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 0  
  
 *period* ::= .
