TOML (Tom’s Obvious, Minimal Language) is a popular configuration file format known for its simplicity and readability. It is widely used in various applications for defining configurations in a structured manner. One of the fundamental data types in TOML is numbers, which can be categorized into integers and floats. In this blog, we will explore TOML numbers in depth with clear explanations and practical examples.

Understanding Numbers in TOML

TOML supports two primary numeric types:

  • Integers: Whole numbers without a fractional or decimal part.
  • Floats: Numbers that include decimal points or are represented in scientific notation.

These numbers are used in configuration files for various applications, such as specifying limits, settings, or numeric identifiers.

TOML Integers

Integers in TOML are whole numbers. They can be:

  • Positive (e.g., +99, 42)
  • Negative (e.g., -17)
  • Zero (e.g., 0, +0, -0 → all are the same)
int1 = +99
int2 = 42
int3 = 0
int4 = -17

Note - Positive integers can be prefixed with a plus sign, while negative integers are always…
