Syntax Description

w

specifies the width of the output field.

Default: 8
Range: 3-8
Tip: If w is 8, an IEEE double-precision, floating-point number is written. If w is 5, 6, or 7, an IEEE double-precision, floating-point number is written, which assumes truncation of the appropriate number of bytes. If w is 4, an IEEE single-precision floating-point number is written. If w is 3, an IEEE single-precision, floating-point number is written, which assumes truncation of one byte.

d

optionally specifies to multiply the number by 10^d.

Details

This format is useful in operating environments where IEEEw.d is the floating-point representation that is used. In addition, you can use the IEEEw.d format to create files that are used by programs in operating environments that use the IEEE floating-point representation.

Typically, programs generate IEEE values in single-precision (4 bytes) or double-precision (8 bytes). Programs perform truncation solely to save space on output files. Machine instructions require that the floating-point number be one of the two lengths. The IEEEw.d format allows other lengths, which enables you to write data to files that contain space-saving truncated data.

Examples

test1=put(x,ieee4.); 
put test1 $hex8.;

test2=put(x,ieee5.); 
put test2 $hex10.;
