Arity

Unary — exp <number>.

exp <number>

Description

Returns e (Euler's number, ~2.71828) raised to the given power. This is the natural exponential function. exp x = e^x. Auto-unwraps shared values.

How It Works

Calls Math.Exp(double). The inverse of log.

Usage

exp 0;                         // 1
exp 1;                         // 2.71828...
exp 2;                         // 7.389...

// Compound continuous growth
_growth = _principal * exp (_rate * _time);

// Logistic / sigmoid
_sigmoid = 1 / (1 + exp (-_x));

// Softmax helper
_sumExp = 0;
{ _sumExp = _sumExp + exp _x } forEach _values;
