A finite IEEE 754 binary64 scalar with canonical language type f64.
Signature
Number remains a source alias for f64 and this host representation remains compatible with native spatial interfaces. Literals without numeric context default to f64. Exact integer widths and f16/f32/f128 use Scalar instead. Numeric variables never implicitly change dtype; use .convert[T]() for an explicit conversion, which rejects overflow and loss of information.
Methods
sin
Returns the numeric result or DataError when the operation cannot be represented.
cos
Returns the numeric result or DataError when the operation cannot be represented.
sqrt
Returns the numeric result or DataError when the operation cannot be represented.
abs
Returns the numeric result or DataError when the operation cannot be represented.
floor
Returns the numeric result or DataError when the operation cannot be represented.
ceil
Returns the numeric result or DataError when the operation cannot be represented.
min
Returns the numeric result or DataError when the operation cannot be represented.
max
Returns the numeric result or DataError when the operation cannot be represented.
clamp
Returns the numeric result or DataError when the operation cannot be represented.
pow
Returns the numeric result or DataError when the operation cannot be represented.
convert
Converts to explicit numeric dtype U or returns DataError when exact conversion fails.
Examples
Calculate a distance
Change either side length and inspect the hypotenuse.
