negate()
negate() changes the sign of a number. There is a method function and a static method function.
Syntax
method function
ba.negate();
static method function
BigArith.negate(n);
Parameters
method function
none
static method function
n - Required - {string|number|BigArith}
The number to negate. It could be a string of digits, a number, or a BigArith object
Return value
method function - {BigArith}
A BigArith object with its value equals to the value of the BigArith object it is called on with the sign changed.
static method function - {BigArith}
A BigArith object with its value equals to the value of n with its sign changed.
Description
There are two functions which could be used, the method function, and the static method function. The method function takes no parameter and returns the value of the BigArith object it is called on with the sign changed.
The static method function takes a parameter n and is always used as BigArith.negate(). It returns the value of n with the sign changed.
A postive number is changed to its negative equivalent and a negative number changes to its positive equivalent.
Any number parameter (that is not strings of digits or a BigArith) should be between the
Number.MIN_SAFE_INTEGERandNumber.MAX_SAFE_INTEGERlimits.
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 method function
var ba = new BigArith("-17031986");
ba = ba.negate(); //BigArith object with value "17031986"
ba = new BigArith("+17031986");
ba = ba.negate(); //BigArith object with value "-17031986"
a = new BigArith("17031986");
ba = ba.negate(); //BigArith object with value "-17031986"
ba = new BigArith(null);
ba = ba.negate(); //BigArith object with value "-0"
ba = new BigArith(0);
ba = ba.negate(); //BigArith object with value "-0"
ba = new BigArith("-0");
ba = ba.negate(); //BigArith object with value "0"
ba = new BigArith(NaN);
ba = ba.negate(); //NaN
Using the static method function
var ba = BigArith.negate("-17031986"); //BigArith object with value "17031986"
ba = BigArith.negate("+17031986"); //BigArith object with value "-17031986"
ba = BigArith.negate("17031986"); //BigArith object with value "-17031986"
ba = BigArith.negate(null); //BigArith object with value "-0"
ba = BigArith.negate(); //BigArith object with value "-0"
ba = BigArith.negate("-0"); //BigArith object with value "0"
ba = BigArith.negate(NaN); //NaN
