Functions

Check if a is comparative to b with the given operator.

Evaluate mathematical strings.

Check if the given value is a valid finite number.

Check if the given value is a "safe" number.

A "safe" number falls within the Number.MAX_SAFE_INTEGER and Number.MIN_SAFE_INTEGER values (Inclusive).

Take an array of numbers and add the values together.

Round a number to the given amount of digits after the decimal point, removing any trailing zeros after the decimal point.

Check if a is comparative to b with the given operator.

Kind: global function
Returns: boolean - true if the comparison matches, false otherwise

Param	Type	Description
a	`number`	The number to compare with `b`
b	`number`	The number to compare with `a`
operator	`string`	A valid comparative operator: `=, <, >, <=, >=, !=, <>`

Example (Is `a` greater than `b`?)

const a = 4;
const b = 2;

compareNumber(a, b, '>'); // true

Example (Is `a` equal to `b`?)

const a = 4;
const b = 2;

compareNumber(a, b, '='); // false

Evaluate mathematical strings.

Kind: global function
Returns: number - The result of the equation

Param	Type	Description
equation	`string`	The mathematical equation to compute.

Example

evaluate('5+6'); // 11

Check if the given value is a valid finite number.

Kind: global function
Returns: boolean - true if it is a finite number, false otherwise

Param	Type
val	`*`

Check if the given value is a "safe" number.

A "safe" number falls within the Number.MAX_SAFE_INTEGER and Number.MIN_SAFE_INTEGER values (Inclusive).

Kind: global function
Returns: boolean - true if the value is a "safe" number, false otherwise

Param	Type
val	`*`

Take an array of numbers and add the values together.

Kind: global function
Returns: number - The summed value

Param	Type
numbers	`Array.<number>`

Round a number to the given amount of digits after the decimal point, removing any trailing zeros after the decimal point.

Kind: global function

Param	Type	Default	Description
num	`number`		The number to round
[precision]	`number`	`0`	The number of digits after the decimal point

Example

toFixed(1.236, 2); // 1.24
toFixed(30.1, 2); // 30.1
toFixed(4.0000000004, 3); // 4
