fp-error
Takes one double and returns two: the top of the stack
is the original argument incremented by one; the second
item on the stack
is the original argument (unchanged).
Converts the signed integer argument (in
AS) to a dou-
ble return value.
Converts the unsigned integer argument (in
AS) to a
double return value.
Converts the double argument
to a signed integer return
value (in
AS). .
Converts the double argument
to an unsigned integer
return value (in
AS).
Converts the signed integer argument (in AS) to a float
return value.
Converts the unsigned integer argument (in
AS) to a
float return value.
Converts the float argument
to a signed integer return
value (in
AS).
Converts the float argument to an unsigned integer re-
turn value (in
AS).
Converts the float argument to a double return value.
Converts the double argument
to a float return value.
Called when
an exception occurs in one of the float-
ing-point math routines. Takes one argument, the error
number. These numbers
are defined by the floating point
package, as is the action of the function (see Appendix
D). This function
is not generally called from user code
but by the floating point package. This function follows
standard calling conventions, so it can be defined en-
tirely in
C.
5.5 Function Call Conventions
All function calls performed in the C. environment follow a strict set of rules
used by the compiler
to avoid corruption of the run-time environment. The
rules depend on
whether arguments are to be passed to a function, whether
the function returns a
value, and the type of the return value (if any).
Figure 5-1 illustrates a
function call.
