How does JavaScript find the logarithm
This article mainly explains "how to find logarithms in JavaScript". Friends who are interested might as well take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "JavaScript how to find the logarithm"!
Find the logarithm method: 1, the use of LN2 attribute, syntax "Math.LN2", can return 2 natural logarithm; 2, the use of LN10 attribute, syntax "Math.LN10"; 3, the use of LOG2E attribute, syntax "Math.LOG2E"; 4, the use of log () method, syntax "Math.log (x)".
The operating environment of this tutorial: windows7 system, javascript1.8.5 version, Dell G3 computer.
JavaScript's method of finding logarithms:
1. Make use of the LN2 property of Math object
The LN2 property is
Can return the natural logarithm of 2 (about 0.693), whose value is similar to 0.69314718055994528623.
Syntax: Math.LN2
2. Use the LN10 property of the Math object
The LN10 property is
The natural logarithm of 10 can be returned (about 2.302), with a value similar to 2.3025850929940459011.
Syntax: Math.LN10
3. Use the LOG2E property of Math object
The LOG2E property is log2e, which returns the logarithm of e with a base of 2 (about 1.4426950408889634).
Syntax: Math.LOG2E
4. Use the LOG10E property of the Math object
The LOG10E property is that returns the logarithm of e with a base of 10 (about 0.434).
Syntax: Math.LOG10E
5. Using the log () method of Math object
The log () method returns the natural logarithm of a number (based on E).
Syntax: Math.log (x)
X: required. Any numeric value or expression.
Returns NaN if x is negative.
If x is 0, return-Infinity.
Example:
Math.log (2)
Can output:
