Display, with a trailing space, the top number on the floating-point stack in scientific notation: <significand><exponent> where:
| <significand> | := | [-]<digit>.<digits0> |
| <exponent> | := | E[-]<digits> |
An ambiguous condition exists if the value of BASE is not (decimal) ten or if the character string representation exceeds the size of the pictured numeric output string buffer.
