<h1 class="topictitle1">FLTFIXDEC (Floating-Point to Fixed Decimal) keyword for display files</h1>
|
|
<div><p>Use this field-level keyword to display a number in an output-capable
|
|
(usage B or O) floating point field in fixed decimal notation.</p>
|
|
<div class="section"><p>This keyword has no parameters.</p>
|
|
<p>The floating-point number
|
|
is first converted to the equivalent number with an exponent of zero. If the
|
|
resulting number (digits and exponent) will fit in the field defined by the
|
|
length and decimal positions values, the number is displayed with the exponent
|
|
suppressed and aligned at the decimal point. If the number will not fit in
|
|
the field defined by the length and decimal position values, the number is
|
|
displayed in standard floating point form, n.nnnnnnE+nnn. When FLTFIXDEC is
|
|
specified, the display length of the field is the DDS length plus 2 (the sign
|
|
and the decimal point). The minimum length of the field is 6.</p>
|
|
<div class="p">When the
|
|
number is too large or small for the fixed-point form specified by FLTFIXDEC
|
|
with the total digits and fractional digits specified for the field, a floating
|
|
point form is displayed that presents the significand as follows. (The significand
|
|
is the string of digits including the sign and decimal point to the left of
|
|
the exponent character E.) <ul><li>Total significand decimal digits: DDS total digits minus 5</li>
|
|
<li>Fractional significand digits: DDS total digits minus 6</li>
|
|
</ul>
|
|
</div>
|
|
<p>FLTFIXDEC has no effect on the input format of the data. Numbers
|
|
can be typed into the field in either fixed point or floating point format.
|
|
When displayed again, however, FLTFIXDEC will be used to determine the display
|
|
format.</p>
|
|
<p>Option indicators are not valid for this keyword.</p>
