The `≥` (greater than equal) operator takes two numbers, variables, or expressions, and tests to see if the first one has a value greater than or equal to the second one. It will return 1 if it is greater than or equal to, and 0 if it is not. When determining the order of operations, `≥` will be executed after the math operators, but it will be executed before the logical operators and in the order that it appears from left to right with the other relational operators.

```
:1≥0
1
:DelVar X3→Y
:X≥Y
0
```

# Advanced Uses

Just like the other relational operators, `≥` can take real numbers and lists for variables. In order to compare the lists, however, both must have the same dimensions; if they don't, the calculator will throw a ERR:DIM MISMATCH error. When comparing a real number to a list, the calculator will actually compare the number against each element in the list and return a list of 1s and 0s accordingly.

```
:{2,4,6,8}≥{1,3,5,7
{1 1 1 1}
:5≥{1,2,3,4,5
{1 1 1 1 1}
```

Unfortunately, `≥` does not work with strings, matrices, or complex numbers (only `=` and `≠` do), and the calculator will actually throw a ERR:DATA TYPE error if you try to compare them. In the case of strings, however, it should be pretty obvious why: a string represents a sequence of characters, and does not associate a value to any character, so there is nothing to compare.

# Error Conditions

**ERR:DATA TYPE**is thrown if you try to compare strings, matrices, or complex numbers.**ERR:DIM MISMATCH**is thrown if you try to compare two lists that have different dimensions.
