What is the exp() method in Dart?
exp() is a dart:math package function that returns the natural exponent, , to the power of a specified number.
Syntax
The syntax of the exp() method is as follows:
double exp(num x)
Parameters
num x: A mandatory numerical value that serves as the power to which the natural exponent, , is raised.
Return value
exp() returns the natural exponent, , raised to the power of x. The result is returned as a double.
exp() returns NaN (Not-A-Number) if x is also NaN.
Code
In the code below, we will demonstrate the use of the exp() method:
// Importing the dart math packageimport "dart:math";// Main functionvoid main(){// Not NaN values or real valuesdouble no1 = 4.00; // Real Numberdouble no2 = 100.00; // Real Numberdouble no3 = 3.50; // Real Number// NaN Valuesdouble no4 = 0/0; // NaNdouble no5 = pow(-2, 0.5); // NaN// Print values returned by the exp() functionprint(exp(no1));print(exp(no2));print(exp(no3));print(exp(no4));print(exp(no5));}
Explanation
In the code above, we call the exp() method with both numerical and NaN arguments.
The function calls to the exp() method in lines return the value of the natural exponent, , raised to the power of the provided parameter.
On the other hand, the function calls in lines provide NaN as the argument, so the exp() method also returns NaN.
