Description

The following javascript code in netbeans 12.5 generates underlining for all the "parseFloat" strings, claiming parseFloat (a standard JavaScript method) is not declared.

"use strict";
let a = parseInt(123);
let f = parseFloat("123.456")
let f1 = parseFloat("123.456").toFixed()
alert(`a=${a}, f=${f}`)

if the ".toFixed()" is removed, parseFloat is recognised.

It doesn't have to be "toFixed"... for instance .indexOf(".") also exhibits this behaviour

Strictly, only lines 4 and 5 are fundamental to this report.
