Category:	numeric
Width range:	1 to 8
Default width:	4
Decimal range:	0 to 10
Alignment:	left
OpenVMS specifics:	twos-complement notation; overflow behavior

Syntax

IBw.d

w: specifies the width of the output field in bytes (not digits).
d: specifies a scaling factor. The scaling factor is optional. When you specify a d value, the IBw.d format multiplies the number by the 10^d value, and then applies the integer binary format to that value.

Details

Negative values are stored in twos-complement notation. If a noninteger value is formatted, rounding occurs. If the value to be formatted is too large to fit in a field of the specified width, then the IBw.d format does the following:

for positive values, it sets the output to the largest positive number that fits in the given width.
for negative values, it sets the output to the negative number of greatest magnitude that fits in the given width.

For more information about OpenVMS native fixed-point values, see HP OpenVMS Programming Concepts Manual, Volume II, Part I, OpenVMS Programming Interfaces: Calling a System Routine.

Example

If you format the value 300 using the IB1. format, you receive the following value:

which is the largest positive value that fits in a byte.

If you format the value -300 using the IB1. format, you receive the following value:

-128
