Number parsing for the AIM expression grammar.

This module provides parsers for numeric literals in the AIM expression language, supporting integers, floating-point numbers, and scientific notation. It handles common number formats with flexible syntax to accommodate various user input styles.

Supported Number Formats

• Integers: 123, -456, 0
• Floats: 12.34, -56.78, .5, -.5, 123.
• Scientific notation: 1e10, 2.5e-3, -1.2E+4, 5E2
• Special values: NaN, Inf, +Inf, -Inf

Examples

42          // integer
-3.14       // float
.5          // float without leading zero
1e6         // scientific notation
-2.5E-3     // scientific notation with negative exponent
NaN         // not a number
Inf         // positive infinity
-Inf        // negative infinity
