trimesh.typed

class trimesh.typed.float64(x=0, /)

Bases: floating, float

Double-precision floating-point number type, compatible with Python float and C double.

Character code:

'd'

Canonical name:

numpy.double

Alias:

numpy.float_

Alias on this platform (Linux x86_64):

numpy.float64: 64-bit precision floating-point number type: sign bit, 11 bits exponent, 52 bits mantissa.

as_integer_ratio()

Return a pair of integers, whose ratio is exactly equal to the original floating point number, and with a positive denominator. Raise OverflowError on infinities and a ValueError on NaNs.

>>> np.double(10.0).as_integer_ratio()
(10, 1)
>>> np.double(0.0).as_integer_ratio()
(0, 1)
>>> np.double(-.25).as_integer_ratio()
(-1, 4)

is_integer() → bool

Return True if the floating point number is finite with integral value, and False otherwise.

New in version 1.22.

Examples

>>> np.double(-2.0).is_integer()
True
>>> np.double(3.2).is_integer()
False

class trimesh.typed.int64

Bases: signedinteger

Signed integer type, compatible with Python int and C long.

Character code:

'l'

Canonical name:

numpy.int_

Alias on this platform (Linux x86_64):

numpy.int64: 64-bit signed integer (-9_223_372_036_854_775_808 to 9_223_372_036_854_775_807).

Alias on this platform (Linux x86_64):

numpy.intp: Signed integer large enough to fit pointer, compatible with C intptr_t.

bit_count() → int

Computes the number of 1-bits in the absolute value of the input. Analogous to the builtin int.bit_count or popcount in C++.

Examples

>>> np.int64(127).bit_count()
7
>>> np.int64(-127).bit_count()
7
