According to the ANSI standard integers do not support an exponent:
integer ::= decimalInteger | radixInteger
decimalInteger ::= digits
digits ::= digit+
radixInteger ::= radixSpecifier 'r' radixDigits
radixSpecifier := digits
radixDigits ::= (digit | uppercaseAlphabetic)+
They even state explicitly that '10e10' is not a valid number token.
Furthermore floating point numbers do not accept a different radix (or
base) and thus are always written in decimal notation:
float ::= mantissa [exponentLetter exponent]
mantissa ::= digits '.' digits
exponent ::= ['-']decimalInteger
exponentLetter ::= 'e' | 'd' | 'q'
