[REG 5.4 - 5.5] QtQuick: Decimal value cannot be correctly set to string parameter

XMLWordPrintable

      If you have a string property in the QtQuick component and you try to set a decimal value to it in JavaScript, it is set validly to an approximate of the value. For example if you set value 3.4 to a string as

      property string myString
...
onSomeSignalHandler: myString = 3.4

      the value of myString is 3.3999999999999999. And for example with 1.1 the value is 1.1000000000000001.

      The problem is not reproducible in Qt 5.4.2.

      An example attached to reproduce the problem.
