tan() [UNSTABLE]

This function is still unstable and in the developmental stage. It takes about computation time for sin + computation time for cos milliseconds to compute tan θ° (which is about for tan 90°).

tan() returns the tangent of an angle (given in degrees). This has only a static method function.

Syntax

method function

BigArith.tan(n);

Parameters

static method function

n - Required - {string|number|BigArith}

The angle (given in degrees). This could be a string of digits, a number, or a BigArith object.

Return value

static method function - {BigArith}

A BigArith object with its value equals to the tangent of the given angle.

Description

There is no method function for tan() so it should ALWAYS be used as a static member function BigArith.tan().

The returned result is the tangent of the angle (given in degrees) to 200 decimal places.

Examples

In the server-side, always remember to add the line var BigArith = require('bigarith.js'); however every other thing remains the same in both server-side and client-side code.

Using static method function

var ba = BigArith.tan("90"); //throws RangeError division by zero
ba = BigArith.tan("45"); //BigArith object with value "1"
ba = BigArith.tan("75.786"); //BigArith object with value "3.94790489515350670109117542623163534465501513035850512311134005400587295700520957954415702735900414306649942878453329557667461916716391291200669582397421401273759999395237647345675059387564486523393406"
ba = BigArith.tan("0"); //BigArith object with value "0"

Method chaining

Since the method returns a BigArith object, method chaining is possible.

var ba = new BigArith("-17031986");
ba = ba.divide("+17031986").add("24011985").multiply("456785564").subtract("2"); //BigArith object with value "10968327654198974"
