EDIT$–Fieldata Image Composition Editing Package
PROC Call
The parameter x specifies the total number of character positions to be occupied by the
edited number, including signs, digits, decimal point, and exponent character. If the
edited numbers require more character positions than specified by the value of x, the
parameter x is ignored, and the required character positions are used.
The parameter y specifies the total number of mantissa digits to appear in the edited
number. It includes the digits on both sides of the decimal point but not the decimal
point itself. The placement of the decimal point within the y digits of the mantissa is
determined by the value in the packet cell FPS. This is the number of digits to appear to
the left of the decimal point. It is normally set to one.
Table 8–4 describes the floating-point editing routines.

Description
Single-precision fixed decimal format.
A1 is edited to fixed decimal format with y digits following the
decimal point, right-justified, in a field of size x.
Double-precision fixed decimal format.
A1, A2 is edited to fixed decimal format with y digits following
the decimal point, right-justified, in a field of size x.
Single-precision generalized format.
Same as scientific format except that an attempt is made to
move the decimal point in such a way as to reduce the
exponent to zero. If this can be done, the exponent is set to
blanks. Otherwise scientific format is used.
Double-precision generalized format.
See EFLG1$ and EFLS2$.
Single-precision, scientific format.
A1 is edited to scientific format with y significant digits in a
field size of x. The exponent is 2 digits long.
Double-precision, scientific format.
A1, A2 is edited to scientific format with y significant digits in
a field size of x. The exponent is 3 digits long.
