示例1: test_add_sub
# 需要导入模块: from sympy.physics.units.quantities import Quantity [as 别名]
# 或者: from sympy.physics.units.quantities.Quantity import convert_to [as 别名]
def test_add_sub():
u = Quantity("u", length, 10)
v = Quantity("v", length, 5)
w = Quantity("w", time, 2)
assert isinstance(u + v, Add)
assert (u + v.convert_to(u)) == (1 + S.Half)*u
# TODO: eventually add this:
# assert (u + v).convert_to(u) == (1 + S.Half)*u
assert isinstance(u - v, Add)
assert (u - v.convert_to(u)) == S.Half*u示例2: test_convert_to
# 需要导入模块: from sympy.physics.units.quantities import Quantity [as 别名]
# 或者: from sympy.physics.units.quantities.Quantity import convert_to [as 别名]
def test_convert_to():
q = Quantity("q1", length, 5000)
assert q.convert_to(m) == 5000*m
assert speed_of_light.convert_to(m / s) == 299792458 * m / s
# TODO: eventually support this kind of conversion:
# assert (2*speed_of_light).convert_to(m / s) == 2 * 299792458 * m / s
assert day.convert_to(s) == 86400*s
# Wrong dimension to convert:
assert q.convert_to(s) == q
assert speed_of_light.convert_to(m) == speed_of_light示例3: test_mul_div
# 需要导入模块: from sympy.physics.units.quantities import Quantity [as 别名]
# 或者: from sympy.physics.units.quantities.Quantity import convert_to [as 别名]

# Pow only supports structural equality:
assert v1 != v2

# TODO: decide whether to allow such expression in the future
# (requires somehow manipulating the core).
#assert u / Quantity(length, 2) == 5

# TODO: Pow only support structural equality:
assert u ** 2 != Quantity("u2", length ** 2, 100)
assert u ** -1 != Quantity("u3", length ** -1, 0.1)
assert u ** 2 == Quantity("u2", length ** 2, 100).convert_to(u)
