Exp Function

Name

Exp Function

function Exp(X: Floating-point type): Extended;

The Exp function computes e ^x. The Exp function is built-in.

Delphi automatically converts Integer and Variant arguments to floating-point. To convert an Int64 argument to floating-point, add 0.0.
If X is a signaling NaN, positive infinity, or negative infinity, Delphi reports runtime error 6 (EInvalidOp).
If X is a quiet NaN, the result is X.
If the result is too large, Delphi reports runtime error 8 (EOverflow).
