A real number (floating-point number) in most programming languages follows this general format:
[digits] → Represents the integer part (optional).
[.digits] → Represents the fractional part (optional).
[(E|e)[(+|-)]digits] → Represents the exponent notation (optional).
This allows real numbers to be written in different forms, such as:
123.456 (Normal decimal representation)
0.789 (Starts with a decimal point)
123E4 (Scientific notation, equivalent to 123 × 10⁴)
3.14e-2 (Equivalent to 3.14 × 10⁻²)
Thus, option (A) [digits][.digits][(E|e)[(+|-)]digits] correctly represents the general syntax for real number representation.
