D language types specify only a minimum precision, not a maximum. The
toPrec() function forces rounding of the argument f to the precision
of the specified floating point type T.
The rounding mode used is inevitably target-dependent, but will be done in
a way to maximize accuracy. In most cases, the default is round-to-nearest.
Parameters
| Name | Description |
|---|---|
| T | precision type to round to |
