Value

from calctex.unit import N, m, Pa
f = 40 & N | 3    # 力   4.00 N     有効数字3桁
s = 2 & m**2 | 4  # 面積 2.000 m^2  有効数字4桁

p = f / s         # 圧力

print(p.tex())
# 2.00 \times 10\,\mathrm{kg \cdot m^{-1} \cdot s^{-2}}
print(p.expect(Pa).tex())
# 2.00 \times 10\,\mathrm{Pa}

Unit

from calctex.unit import *

print(N == kg*m*s**-2)
# True
print(Pa == N/m**2)
# True

roundtex

from calctex.common import roundtex

print(roundtex(100, significant=2))
# 1.0 \times 10^{2}
