typemin

Return the minimum value of a specified numeric type.

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 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 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
