+--TEST--
+Test for retrieving encrypted data of binary types with different sizes as output parameters
+--DESCRIPTION--
+Test implicit conversions between different binary types of different sizes
+With Always Encrypted, implicit conversion works if:
+1. From a binary(m) column to a SQLSRV_SQLTYPE_BINARY(n) output parameter where m == n
+2. From a binary(m) column to a SQLSRV_SQLTYPE_VARBINARY(n) output parameter where m == n
+3. From a varbinary(m) column to a SQLSRV_SQLTYPE_BINARY(n) output parameter where m == n
+4. From a varbinary(m) column to a SQLSRV_SQLTYPE_VARBINARY(n) output parameter where m == n
+Without AlwaysEncrypted, implicit conversion works if:
+1. From a binary(m) column to a SQLSRV_SQLTYPE_BINARY(n) output parameter where m, n == any value
+2. From a binary(m) column to a SQLSRV_SQLTYPE_VARBINARY(n) output parameter where m <= n (exclude SQLSRV_SQLTYPE_VARBINARY('max'))
+3. From a varbinary(m) column to a SQLSRV_SQLTYPE_BINARY(n) output parameter where m, n == any value
+4. From a varbinary(m) column to a SQLSRV_SQLTYPE_VARBINARY(n) output parameter where m, n == any value

+--TEST--
+Test for retrieving encrypted data of float types with different number of bits as output parameters

+Test implicit conversions between different number of bits
+With Always Encrypted, implicit conversion works if:
+1. From a float(m) column to a SQLSRV_SQLTYPE_FLOAT output parameter where m > 24
+Without Always Encrypted, implicit conversion between different number of bits works
