Converts a double value to UInt64 correctly.
Example 
// set d to a very high UInt64 value
dim d as Double = pow(256.0,8.0)  - 10000

// RB will convert to Int64 here! so number is cut to 9... instead of 18...
dim u1 as UInt64 = d

// plugin does it right
dim u2 as UInt64 = DoubleToUInt64MBS(d)

MsgBox str(u1)+" "+str(u2)

Xojo converts UInt64 to Double with an intermediate Int64 which breaks big numbers. This function does it correctly.
