IBw.d

Category	numeric
Width range:	1-8
Default width:	4
Decimal range:	0-10
Alignment:	left
Windows specifics:	native floating-point representation

w

specifies the width of the output field in bytes (not digits).

d

optionally specifies a scaling factor. When you specify a d value, the IBw.d format multiplies the number by 10^d, and then applies the integer binary format to that value.

Details

The IBw.d format converts a double-precision number and writes it as an integer binary (fixed-point) value. Integers are stored in integer-binary (fixed-point) form.

For more information about microcomputer fixed-point values, see Intel Corporation's i486 Microprocessor Programmer's Reference Manual.

Examples

Example 1: Processing a Positive Number

If you format 1.0 as the double-precision number, it is stored as an integer:

01 00 00 00 00 00 00 00

(Remember, Windows stores binary data in byte-reversed order.) The value written depends on the w value you specify.

If you specify the IB4. format, you receive the following value:

01 00 00 00

If you specify the IB2. format, you receive the following value:

01 00

Example 2: Processing a Negative Number

If you try to format -1 with the IB4. format, you receive the following value:

FF FF FF FF

If you specify the IB2. format, you receive the following value:

FF FF
