#format_seconds(float, precision = nil) ⇒ String

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Formats seconds to have 5 digits of precision with trailing zeros removed if the number is less than 1 or with 2 digits of precision if the number is greater than zero.

The precision used is set in SUB_SECOND_PRECISION and DEFAULT_PRECISION.

Examples:

format_seconds(0.000006) #=> "0.00001"
format_seconds(0.020000) #=> "0.02"
format_seconds(1.00000000001) #=> "1"

Parameters:

  • float (Float)

Returns:

  • (String) —

    formatted float
