Yes, it’s called if .. then .. else In fact in F# everything is an expression, even an if .. then .. else block. In C# var x = true ? 0 : 1; In F# let x = if true then 0 else 1 So in your case: let y = Seq.groupBy (fun x … Read more
Oracle doesn’t provide such IIF Function. Instead, try using one of the following alternatives: DECODE Function: SELECT DECODE(EMP_ID, 1, ‘True’, ‘False’) from Employee CASE Function: SELECT CASE WHEN EMP_ID = 1 THEN ‘True’ ELSE ‘False’ END from Employee
you can use && operator – second operand expression is executed only if first is true direction == “right” && slideOffset += $(“.range-slide”).width() in my opinion if(conditon) expression is more readable than condition && expression
The ternary operator is used to return values and those values must be assigned. Assuming that the methods doThis() and doThat() return values, a simple assignment will fix your problem. If you want to do what you are trying, it is possible, but the solution isn’t pretty. int a = 5; int b = 10; … Read more
This is a GNU C extension (see ?: wikipedia entry), so for portability you should explicitly state the second operand. In the ‘true’ case, it is returning the result of the conditional. The following statements are almost equivalent: a = x ?: y; a = x ? x : y; The only difference is in … Read more
MatLab doesn’t have a ternary operator, or any other syntactic sugar for one-line if-statements. But if your if-statement is really simple, you could just write it in one line anyway: if (cond); casetrue(); else; casefalse(); end It’s not as simple as ternary operator, but still better than writing it in 5 lines of code.
This is the conditional operator. $x ? $y : $z means “if $x is true, then use $y; otherwise use $z“. It also has a short form. $x ?: $z means “if $x is true, then use $x; otherwise use $z“. People will tell you that ?: is “the ternary operator”. This is wrong. ?: … Read more
C# language specification, version 5, section 6.1.9: An implicit constant expression conversion permits the following conversions: A constant-expression (ยง7.19) of type int can be converted to type sbyte, byte, short, ushort, uint, or ulong, provided the value of the constant-expression is within the range of the destination type. Your first example is a constant expression, … Read more
You can convert a lambda expression to a particular target delegate type, but in order to determine the type of the conditional expression, the compiler needs to know the type of each of the second and third operands. While they’re both just “lambda expression” there’s no conversion from one to the other, so the compiler … Read more
|| is the conditional OR operator in C# You probably had a hard time finding it because it’s difficult to search for something whose name you don’t know. Next time try doing a Google search for “C# Operators” and look at the logical operators. Here is a list of C# operators. My code is: if … Read more
