What is libjs-d3-format
libjs-d3-format is:
Sometimes JavaScript doesn’t display numbers the way you expect. For example, printing tenths with a naive simple loop might give you 0, 0.1, 0.2, 0.30000000000000004, 0.4, 0.5, 0.6000000000000001, 0.7000000000000001, 0.8, 0.9 - welcome to binary floating point!
Yet rounding error is not the only reason to customize number formatting. A table of numbers should be formatted consistently for comparison; above, 0.0 would be better than 0. Large numbers should have grouped digits (e.g., 42,000) or be in scientific or metric notation (4.2e+4, 42k). Currencies should have fixed precision ($3.50). Reported numerical results should be rounded to significant digits (4021 becomes 4000). Number formats should appropriate to the reader’s locale (42.000,00 or 42,000.00). The list goes on.
Formatting numbers for human consumption is the purpose of d3-format, which is modeled after Python 3’s format specification mini-language (PEP 3101).
