Question:medium

Which of the following is invalid floating point constant?

Show Hint

In exponential notation, the exponent must always be an integer. Examples: \(2.5E3\), \(1.4E-2\), \(5e+7\) are valid, but \(2.5E3.5\) is invalid.

Updated On: Jun 25, 2026

\(0.65e4\)
\(1.5e+5\)
\(18E+3.5\)
\(-1.2E-1\)

Show Solution

The Correct Option is C
