Example 41 with Nullable

use of javax.annotation.Nullable in project storm by apache.

the class TestExprSemantic method testJDBCNumericFunctions.

@Test
public void testJDBCNumericFunctions() throws Exception {
    Values v = testExpr(Lists.newArrayList("{fn POWER(3, 2)}", "{fn ABS(-10)}", "{fn MOD(10, 3)}", "{fn MOD(-10, 3)}"));
    assertEquals(new Values(9.0d, 10, 1, -1), v);
    // Belows are floating numbers so comparing this with literal is tend to be failing...
    // Picking int value and compare
