w.d

Numeric
Width range:	1- 32
Decimal range:	0- 31, d < w.
CMS specifics:	minimum and maximum values

w

specifies the field width of the input value in bytes or character digits.

d

specifies the number of digits to the right of the decimal point in the input value.

Details

Numbers are interpreted using the EBCDIC character-encoding system, with one digit per byte. The w.d informat reads numeric values located anywhere in the field. Blanks can precede or follow a numeric value with no effect. A minus sign with no separating blanks must immediately precede a negative value. Data can be stored with decimal points or in scientific notation.

Include a d value in the w.d informat when you want SAS to insert a decimal point. When you include a d value, values read without decimal points are divided by 10^d. If the value read already has a decimal point, the d is ignored.

The range of acceptable values that can be read with the w.d informat can range from 5.398E-79 to 7.237E+75. The following table illustrates the use of the w.d informat.

Data Pattern Read		Actual Numeric Value	Informat	Resulting Numeric Value
'F1F2F3F4'x		1234	4.	1234
'40F1F2F3F4'x		1234	5.	1234
'F1F24BF5F0'x		12.50	5.	12.50
'F1F24BF5F0'x		12.50	5.1	12.50
'F1F2F5F040'x		1250	5.1	125
'40F1F0F0F0'x		1000	5.1	100
'4060F1F2F3F4'x		-1234	6.	-1234
'40F14BF0C54EF0F3'x		1.0E+03	8.	1000
