Converts number to an engineering format, floating-point string at least width characters wide or wider if necessary.
Engineering format is similar to E format (exponential notation), except the exponent is a multiple of three (..., –3, 0, 3, 6, ...). The connector pane displays the default data types for this polymorphic function.
Inputs/Outputs
use system decimal point (T)
—
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
—
number can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on. 
width (-)
—
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 (6)
—
precision must be numeric. The function rounds the number of digits after the decimal point of the output string to precision. 
Engineering string
—
Engineering string is the resulting string. The following table shows how the values of number, width, and precision affect Engineering string. In this table, the underline character ( _ ) represents a space in Engineering string.
