colour.utilities.as_float#
- colour.utilities.as_float(a: ArrayLike, dtype: Type[DTypeFloat] | None = None) NDArrayFloat [source]#
Attempt to convert given variable \(a\) to
numpy.floating
using givennumpy.dtype
. If variable \(a\) is not a scalar or 0-dimensional, it is converted tonumpy.ndarray
.- Parameters:
a (ArrayLike) – Variable to convert.
dtype (Type[DTypeFloat] | None) –
numpy.dtype
to use for conversion, default to thenumpy.dtype
defined by thecolour.constant.DEFAULT_FLOAT_DTYPE
attribute.
- Returns:
Variable \(a\) converted to
numpy.floating
.- Return type:
Examples
>>> as_float(np.array(1)) 1.0 >>> as_float(np.array([1])) array([ 1.]) >>> as_float(np.arange(10)) array([ 0., 1., 2., 3., 4., 5., 6., 7., 8., 9.])
