Problem Description:
RandRange does not cope with negative ranges.
Steps to Reproduce:
{code:java}
<cfscript>
// RANGE -10 to -9
i = 0;
r = [];
while(i<10) {
i++;
r[i] = randRange(-10,-9);
}
writeDump(r); // outputs [-8,-8,-9,-8,-9,-9,-9,-8,-9,-8]
// RANGE -1 to 0
i = 0;
r = [];
while(i<10) {
i++;
r[i] = randRange(-1,0);
}
writeDump(r); // outputs [0,0,0,0,0,0,0,0,0,0]
// RANGE 0 to -1
i = 0;
r = [];
while(i<10) {
i++;
r[i] = randRange(0,-1);
}
writeDump(r); // outputs [0,0,0,0,0,0,0,0,0,0]
</cfscript>
{code}
Actual Result:
See inline comments on code above
Expected Result:
Integers within the specified range
Any Workarounds:
<cfscript>
int(0 - randRange(0,1));
