# FHIRPath Operator: >= (greater-or-equal)
The greater or equal operator (`>=`) returns `true` if the first operand is greater than or equal to the second. The operands must be of the same type, or convertible to the same type using implicit conversion.

``` fhirpath
10 >= 5 // true
10 >= 5.0 // true - note the 10 is converted to a decimal to perform the comparison
'abc' >= 'ABC' // true
4 'm' >= 4 'cm' // true (or { } if the implementation does not support unit conversion)

@2018-03-01 >= @2018-01-01 // true
@2018-01-01 >= @2018-01-01 // true - equal with same precision
@2018-03 >= @2018-03-01 // empty ({ }) - different precisions
@2018-03-01T10:30:00 >= @2018-03-01T10:00:00 // true
@2018-03-01T10 >= @2018-03-01T10:30 // empty ({ }) - different precisions
@2018-03-01T10:30:00 >= @2018-03-01T10:30:00.0 // true - values are equal to seconds, trailing zeroes after the decimal are ignored

@T10:30:00 >= @T10:00:00 // true
@T10 >= @T10:30 // empty ({ }) - different precisions
@T10:30:00 >= @T10:30:00.0 // true - values are equal to seconds, trailing zeroes after the decimal are ignored

## Summary
- **Category**: Comparison
- **Section**: `6.2.4`
- **Left Argument**: `String | Integer | Decimal | Quantity | Date | DateTime | Time`
- **Right Argument**: `String | Integer | Decimal | Quantity | Date | DateTime | Time`
- **Return Type**: `Boolean`
- **Empty Input Result**: `empty`
- **Errors on Multiple Input**: `true`
## Description
Returns `true` if the first operand is greater than or equal to the second. The operands must be of the same type, or convertible to the same type using implicit conversion. Both arguments must be collections with single values. String ordering is strictly lexical based on Unicode values.
## Type Mapping
- `String-String`
- `Integer-Integer`
- `Integer-Decimal`
- `Decimal-Integer`
- `Decimal-Decimal`
- `Quantity-Quantity`
- `Date-Date`
- `DateTime-DateTime`
- `Time-Time`
