|SYNTAX|| NumToStr( NUMBER, format = 1.3, separator=True, roundAndPad = False )
NumToStr( ARRAY, format = 1.3, separator=True, roundAndPad = False )
|FUNCTION|| It is used to convert numeric value of NUMBER or ARRAY to string.
The second parameter - format - allows you to control output formatting (decimal places and leading spaces). The integer part of the number controls minimum number of characters used to display the number (if you specify high number the output will be space-padded). The fractional part defines how many decimal places to display, for example 1.0 - will give you a number without fractional part at all, and 1.2 - will give two digits past the decimal point
There is also a special format constant formatDateTime that allows to convert date/time returned by DateTime() function formatted according to Windows regional settings.
Since 6.20 also supported is formatDateTimeISO which will return date time in international format (ISO) i.e, YYYY-MM-DD HH:MM:SS
Third parameter separator (true by default) controls if thousand separator is added or not.
Fourth parameter roundAndPad controls whenever function rounds output beyond 7th significant digit (and pads the rest with zeros), By default rounding is OFF now because it was off in 5.90 and earlier and rounding introduced in 5.91 could confuse old time users
Note: NumToStr is a synonym for WriteVal function.
