A stricter `parseInt` and `parseFloat`.
npm install numero> A stricter parseInt and parseFloat.
``js
numero.parseInt(42); // 42
numero.parseInt('42'); // 42
numero.parseInt('42 '); // 42
numero.parseInt(3.14); // null
numero.parseInt('3.14'); // null
numero.parseInt(' 3.14'); // null
numero.parseFloat(42); // 42
numero.parseFloat('42'); // 42
numero.parseFloat('42 '); // 42
numero.parseFloat(3.14); // 3.14
numero.parseFloat('3.14'); // 3.14
numero.parseFloat(' 3.14'); // 3.14
`
1. null is returned if x cannot be parsed to an integer/float.
2. An integer is also a float.
3. x can have trailing/leading whitespace.
Numero is stricter than the native parseInt and parseFloat in that extraneous characters are not allowed. For example:
`js
parseInt('42foo', 10); // 42
numero.parseInt('42foo'); // null
parseFloat('3.14foo'); // 3.14
numero.parseFloat('3.14foo'); // null
`
Numero can also handle numbers in their octal and hexadecimal representations, and negative numbers too:
`js`
numero.parseInt('052'); // 42
numero.parseFloat('-0x2a'); // -42
