50e1

50e1 is a numeric literal commonly used in programming and data formats to express the decimal number 500 in scientific notation. In this notation, the value is equal to the mantissa 50 multiplied by 10 raised to the power of 1.

The form is supported in many programming languages (for example Python, JavaScript, Java, C, C++, JSON). It denotes a floating-point number rather than an integer, and the exact type may be double or float depending on language and context.

Equivalents include 5e2 and 500.0.

Examples: In Python, evaluating 50e1 yields 500.0; in JavaScript, 50e1 yields 500.

Notes: The exponent part uses e or E, may have a sign; the exponent is an integer.

The notation is widely supported for floating-point literals; using it with an integer context may implicitly convert to floating-point.

In JSON, 50e1 is valid and represents 500.

Edge cases: extremely large exponents can overflow to Infinity; very small exponents can underflow to 0.
