dtypes2signatures

Transform a list of array argument data types into a list of signatures.

Installation

npm install @stdlib/ndarray-base-dtypes2signatures

Usage

var dtypes2signatures = require( '@stdlib/ndarray-base-dtypes2signatures' );

dtypes2signatures( dtypes, nin, nout )

Transforms a list of array argument data types into a list of signatures, where nin is the number of input array arguments and nout is the number of output array arguments.

var dtypes = [ 'float32', 'float64' ];

var out = dtypes2signatures( dtypes, 1, 1 );
// returns [ '(float32) => (float64)' ]

out = dtypes2signatures( dtypes, 2, 0 );
// returns [ '(float32, float64) => ()' ]

out = dtypes2signatures( dtypes, 0, 2 );
// returns [ '() => (float32, float64)' ]
