typemin
Return the minimum value of a specified numeric type.
Installation
npm install @stdlib/utils-type-min
Usage
var typemin = require( '@stdlib/utils-type-min' );
typemin( dtype )
Returns the minimum value of a specified numeric type.
var m = typemin( 'int8' );
// returns -128
The following numeric types are supported:
float64
: double-precision floating-point numbersfloat32
: single-precision floating-point numbersfloat16
: half-precision floating-point numbersint32
: 32-bit two's complement signed integersuint32
: 32-bit unsigned integersint16
: 16-bit two's complement signed integersuint16
: 16-bit unsigned integersint8
: 8-bit two's complement signed integersuint8
: 8-bit unsigned integersuint8c
: 8-bit unsigned integers clamped to0-255
Examples
var typemin = require( '@stdlib/utils-type-min' );
var m = typemin( 'float64' );
// returns -Infinity
m = typemin( 'float32' );
// returns -Infinity
m = typemin( 'float16' );
// returns -Infinity
m = typemin( 'int32' );
// returns -2147483648
m = typemin( 'uint32' );
// returns 0
m = typemin( 'int16' );
// returns -32768
m = typemin( 'uint16' );
// returns 0
m = typemin( 'int8' );
// returns -128
m = typemin( 'uint8' );
// returns 0
m = typemin( 'uint8c' );
// returns 0
