toPrec

fnT toPrec(T: float)(float f) @nogc nothrow @safe pure

Round argument to a specific precision.

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

`T`	precision type to round to
`f`	value to convert

Returns

f in precision of type T
