Constants defined in dart-math library

Constants defined in dart:math library:

dart:math library provides a couple of mathematical constants, functions and a random number generator. In this post, we will check the constants of dart:math with example.

Constants in dart:math :

Following are the constants defined in dart:math :

e → const double:

This is the base of the natural algorithm.

ln2 → const double:

This is the natural logarithm of 2.

ln10 → const double:

Natural logarithm of 10.

log2e → const double:

Base 2 logarithm of e.

log10e → const double:

Base 10 logarithm of e.

pi → const double:

Value of PI.

sqrt1_2 → const double:

Square root of 1/2

sqrt2 → const double:

Square root of 2.

Let’s take a look at the example below:

import 'dart:math';
  
void main() {
  print("e : ${e}");
  print("ln2 : ${ln2}");
  print("ln10 : ${ln10}");
  print("log2e : ${log2e}");
  print("log10e : ${log10e}");
  print("pi : ${pi}");
  print("sqrt1_2 : ${sqrt1_2}");
  print("sqrt2 : ${sqrt2}");
}

This program is printing the values of all constants of dart:math.

e : 2.718281828459045
ln2 : 0.6931471805599453
ln10 : 2.302585092994046
log2e : 1.4426950408889634
log10e : 0.4342944819032518
pi : 3.141592653589793
sqrt1_2 : 0.7071067811865476
