EXP()

All functions > MATH > EXP()

Returns e raised to the power of the given number.

Signatures

Exponential

Returns: Value of e^exponent

EXP(exponent: T) → DOUBLE

With:

• T : Floating-point type (FLOAT, DOUBLE)

Signature notes:

• EXP(0.0) = 1
• Inverse of the natural logarithm: EXP(LN(x)) = x
• Returns NULL if the input is NULL
• Can overflow to infinity for large exponents

Examples

SELECT
    f1 := EXP(0.0E0), -- e^0 equals 1
    f2 := EXP(1.0E0), -- e^1 equals e
    f3 := EXP(2.0E0), -- e squared
    f4 := EXP(-1.0E0) -- Negative exponent
