xcall FP_CMP(result, float1, float2)
Returned with one of the following values: (n)
0 = Float1 equals float2.
-1 = Float1 is less than float2.
1 = Float1 is greater than float2.
A native floating-point number to compare to float2. (a8)
A native floating-point number to be compared to float1. (a8)
The FP_CMP subroutine compares two floating-point numbers to see if they are equal or if one is greater than the other.
Result, float1, and float2 are native floating-point numbers represented as a8 variables.
This routine can also be called as a function.
Before you can use a subroutine as a function, you must first declare it external:
external function fp_cmp ,d
Then you can use FP_CMP as follows:
if (%fp_cmp(float1, float2)) then writes(TTCHN, "not equal") else writes(TTCHN, "equal")
