Function core.math.toPrec

Round argument to a specific precision.

T toPrec(T) (
  float f
);

T toPrec(T) (
  double f
);

T toPrec(T) (
  real f
);

T toPrec(T) (
  float f
);

T toPrec(T) (
  double f
);

T toPrec(T) (
  real f
);

T toPrec(T) (
  float f
);

T toPrec(T) (
  double f
);

T toPrec(T) (
  real f
);

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

NameDescription
T precision type to round to
f value to convert

Returns

f in precision of type T
