Zw.d Format

Writes standard numeric data with leading 0s.

Category:	Numeric
Alignment:	Right
Interaction:	When the DECIMALCONV= system option is set to STDIEEE, the output that is written using this format might differ slightly from previous releases. For more information, see DECIMALCONV= System Option in SAS System Options: Reference.

Zw.d

Syntax Description

w

specifies the width of the output field.

Default	1
Range	1–32
Tip	Allow enough space to write the value, the decimal point, and a minus sign, if necessary.

d

specifies the number of digits to the right of the decimal point in the numeric value. This argument is optional.

Default	0
Range	0–31
Tip	If d is 0 or you omit d, Zw.d writes the value without a decimal point.

Details

The Zw.d format writes standard numeric values one digit per byte and fills in 0s to the left of the data value.

The Zw.d format rounds to the nearest number that fits into the output field. If w.d is too large to fit, SAS might shift the decimal to the BESTw. format. The Zw.d format writes negative numbers with leading minus signs. In addition, it right aligns before writing and pads the output with leading zeros.

Comparisons

The Zw.d format is similar to the w.d format except that Zw.d pads right-aligned output with 0s instead of blanks.

Example
