Template:Len

From Meta, a Wikimedia project coordination wiki

This template determines the number of digits before the decimal point excluding leading zeros in non-negative numbers with a maximum of 15. It's designed to be used in template development, its code should be substituted inline.

Result -1: Value < 0, error. Non-negative numbers incl. 0 yield at least 0.

Result  0: Value < 1 (10^0), negative exponents like -2 for 0.01 not supported.

Result  1: Value < 10 (10^1), especially 1 up to 9.

Result  2: Value < 100 (10^2), especially 10 up to 99.

Result  3: Value < 1000 (10^3), especially 100 up to 999.

Result 15: Value < 10^15

Result 16: 10^15 <= value, see accuracy.

Examples:

{{ Len|-.1}} = -1

{{ Len|0.0}} = 0

{{ Len|+.1}} = 0

{{ Len|1.0}} = 1

{{ Len|123}} = 3

{{ Len|0123}} = 3

{{ Len|7*3}} = 2

{{ Len|20091203210243}} = 14 (timestamp)

{{ Len|1234567890.234567}} = 10

{{ Len|123456789012345.7}} = 15

{{ Len|1234567890123456.}} = 16 (out of range)

{{ Len|12345678901234567}} = 16 (out of range)
