3042	Number(): Remarks needs rework	c.haslam	Jpm	"Remarks says: ''A string beginning with digits has non-numeric characters stripped''. I read this to mean that Number('12cat34') returns 1234, but it actually returns 12.

Remarks says ''Default behavior results in auto-sized integer.'' But Number() returns floating-point for e.g. Number('12.34').

So I suggest that Remarks be replaced by:

''If the expression is a number, a number is returned.

''If the expression is a string, Number() scans the string, rightward, starting from the left end, for characters that can constitute a number, starting from the left end. It stops scanning at the first character that cannot be part of a number.''

''In its scanning, Number() accepts a leading + (or -) sign, but not commas. If the first character cannot be part of number, Number() returns zero.''

''By default, for expressions that can be evaluated to an integer, Number() returns a type based on the size of the number: a 32-bit integer if the number will fit in a 32-bit integer, else a 64-bit integer.''"	Bug	closed	3.3.13.21	Documentation	3.3.13.20	None	Fixed
