asNumber

text |> number | nothing

Turns a text into a number. If the text can't be parsed as a number, returns nothing.

Example

import { asNumber } from 'text'

from '123' asNumber
// Returns: 123

from '123.45' asNumber
// Returns: 123.45

from '-42' asNumber
// Returns: -42

from '1.23E+2' asNumber
// Returns: 123

from 'not a number' asNumber
// Returns: nothing

from '' asNumber
// Returns: nothing

Notes

• Supports standard decimal numbers (positive and negative)
• Handles whitespace around numbers (e.g., ' 123 ' becomes 123)
• Supports scientific notation (e.g., '1.23E+2' becomes 123)
• Returns nothing for invalid input (empty strings, non-numeric text, etc.)
• Uses invariant culture for consistent parsing across different locales
