FIXED(*) Variables

pTAL treats a FIXED(*) variable in an expression as FIXED:

FIXED(*) f1 := 123F;

FIXED(2) f2;

f2 := f1; ! F2 is assigned 123.00

pTAL does not perform scaling on data stored into a FIXED(*) variable:

FIXED(2) f1 := 1.23F;

FIXED(*) f2;

FIXED f3;

f2 := f1; ! F2 is assigned 123

f3 := f1; ! F3 is assigned 1

Example 4-2. FIXED(*) Variables

FIXED(*) f1;

FIXED(3) f2 := 1.234F;

f1 := f2; ! f1 = 1234

f2 := f1; ! f2 = 1234.000

f1 := f2; ! f1 = 1234000

f2 := f1; ! f2 = 1234000.000

f1 := f2; ! f1 = 1234000000

f2 := f1; ! f2 = 1234000000.000
