	use system decimal point defines the decimal separator. If TRUE (default), the decimal separator uses the localized decimal separator. If FALSE, the decimal separator is a period.
	number can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.
	width must be numeric. If unwired, the function uses exactly as many digits as are needed to represent the number, with no extra padding.
	precision must be numeric. The function rounds the number of digits after the decimal point of the output string to precision.
	E-format string is the resulting string. The following table shows how the values of number, width, and precision affect E-format string. In this table, the underline character ( _ ) represents a space in E-format string. number width precision E-format string Comments 4.911 5 2 4.91e0 number is rounded, width is extended. .003926 10 2 _ _ _3.93e–3 number is rounded, padded with spaces on the left. 216.01 5 0 _ _2e2 number is rounded, padded with spaces on the left.
