Template:Order of magnitude

Template documentation

Usage

This template calculates the (decimal) order of magnitude of numbers within the ranges 10³⁰⁰ to 10⁻³⁰⁰ and −10⁻³⁰⁰ to −10³⁰⁰.

The template currently gives 0 for 0. Do not rely on this, however, because this mathematically incorrect result is under review (see talk).

Examples

• {{Order of magnitude|123400}} → 5 [1]
• {{Order of magnitude|12340}} → 4 [2]
• {{Order of magnitude|1234}} → 3 [3]
• {{Order of magnitude|123.4}} → 2 [4]
• {{Order of magnitude|12.34}} → 1 [5]
• {{Order of magnitude|1.234}} → 0 [6]
• {{Order of magnitude|.1234}} → -1 [7]
• {{Order of magnitude|.01234}} → -2 [8]
• {{Order of magnitude|0}} → 0 [9]
• {{Order of magnitude|}} → [10]
• {{Order of magnitude}} gives 0 [11]
