Example
Double Precision Decrement
-FP-DECR
double1
double1, double2
double1 - 1
-+ double2
This function takes a double-precision
floating-point number and decre-
ments it by one. The original
input is left untouched as the second item
on the stack. The result
is at the top of the argument stack after execution
of this function.
None.
There
are no errors generated in - FP - DECR because - FP - DECR merely
pushes a double-precision binary
floating-point one onto the argument
stack and
calls -FP-MINUS. Errors are therefore detected as in
-FP-MINUS.
The following is an example of C code which would generate a call to
-FP-DECR.
