2024.6.21 四則演算の速度比較

code:operand1.py

import time

loopmax = 100000000

#

time1_init = time.process_time()

for i in range(loopmax):

y = 2.0 + 3.0

time1 = time.process_time() - time1_init

print('+ :', time1)

#

time2_init = time.process_time()

for i in range(loopmax):

y = 2.0 - 3.0

time2 = time.process_time() - time2_init

print('- :', time2)

#

time3_init = time.process_time()

for i in range(loopmax):

y = 2.0 * 3.0

time3 = time.process_time() - time3_init

print('* :', time3)

#

time4_init = time.process_time()

for i in range(loopmax):

y = 2.0 / 3.0

time4 = time.process_time() - time4_init

print('/ :', time4)
