libjs-d3-format - 1:1.4.1-7 main

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).
