0-10
double1, double2, op
int
If (double1 op double2). then 1 -+ int
Else 0 --> int
where op is defined as follows:
1
== equal
2
I = not equal
3
< = .less than or equal
4
< less than
5
> = greater than or equal
6 > greater than .
This function takes two double-precision floating-point numbers and
compares them according to a third
input. op. The integer result is zero if
the comparison is false and one if it is true. The inputs doubleT and double2
are compared according to op, with doubleT being the leftmost argument.
None.
The subset
of extended real numbers representable by the TMS34010
double-precision floating-point format forms a well ordered set.
The
following is an example of C code which would generate a call to
...,FP-COMPARE.
main( )
[
double a,b;
if (a < b) ;
/* declare two double
precision floating
point numbers * /
/* OP = 2 when -FP-COMPARE
is called * /
/* end of main * /
