Conversion to string

A boolean, integer, or double in a string context converts to a string. (Remember, the boolean values true and false are not strings. See Boolean data.)
'The result is ' + true                         evaluates to 'The result is true'
FALSE (in an input field that requires a string) converts to 'FALSE'
'The answer is ' + 15                           evaluates to 'The answer is 15'
22 (in an input field that requires a string)   converts to  '22'
('4.5' == .45e1)                                evaluates to true
14,52 (in an input field that requires a string) evaluates to'14,52'
