how can I Implement the ln(x) in flutter? Can I use Math package?

I know that ln(x) = Loge(x)

Not found package to do that for me

CodePudding user response：

Use import 'dart:math';.

See https://api.flutter.dev/flutter/dart-math/dart-math-library.html

CodePudding user response：

You can use dart:math for this things . I found this you can investigate https://api.flutter.dev/flutter/dart-math/ln10-constant.html

CodePudding user response：

The log function from dart:math already gives you the natural logarithm:

Converts x to a double and returns the natural logarithm of the value.

And you can easily verify that log(e) returns 1.0.

CodePudding user response：

With dart:math, you can use the e constant and the log() method to implement the ln() method.

log(x) divided by log(e) gives ln(x)

double ln(num x) => log(x) / log(e);
