| System.Single Structure |
|
| |
| Description | |
|
The Single structure holds floating point numbers in the range +/-3.402823e38, plus the following extreme values :
| PositiveInfinity | Infinity (N/0) |
| NegativeInfinity | -Infinity (-N/0) |
| NaN | Not a number (0/0) |
Single complies with IEEE standards for calculations.
Unlike the Decimal structure, rounding can occur with Single value calculations.
Single structures are created dynamically from their definition - there is no Create constructor. The native delphi Single type maps to System.Single.
