|
|
Converts a boolean to a string using optionally supplied arguments. The
|
|
optional second and third arguments represent what true and false will be
|
|
converted to respectively. If only one argument is given, it will be
|
|
converted from a boolean to a string containing 'true' or 'false'.
|
|
|
|
*Examples:*
|
|
|
|
bool2str(true) => 'true'
|
|
bool2str(true, 'yes', 'no') => 'yes'
|
|
bool2str(false, 't', 'f') => 'f'
|
|
|
|
Requires a single boolean as an input.
