@stdlib/utils-type-max NPM

typemax

Return the maximum value of a specified numeric type.

Installation

npm install @stdlib/utils-type-max

Usage

var typemax = require( '@stdlib/utils-type-max' );

typemax( dtype )

Returns the maximum value of a specified numeric type.

var m = typemax( 'int8' );
// returns 127

The following numeric types are supported:

float64: double-precision floating-point numbers
float32: single-precision floating-point numbers
float16: half-precision floating-point numbers
int32: 32-bit two's complement signed integers
uint32: 32-bit unsigned integers
int16: 16-bit two's complement signed integers
uint16: 16-bit unsigned integers
int8: 8-bit two's complement signed integers
uint8: 8-bit unsigned integers
uint8c: 8-bit unsigned integers clamped to 0-255

Examples

var typemax = require( '@stdlib/utils-type-max' );

var m = typemax( 'float64' );
// returns Infinity

m = typemax( 'float32' );
// returns Infinity

m = typemax( 'float16' );
// returns Infinity

m = typemax( 'int32' );
// returns 2147483647

m = typemax( 'uint32' );
// returns 4294967295

m = typemax( 'int16' );
// returns 32767

m = typemax( 'uint16' );
// returns 65535

m = typemax( 'int8' );
// returns 127

m = typemax( 'uint8' );
// returns 255

m = typemax( 'uint8c' );
// returns 255

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
