import math
result = math.copysign(5, -3)
print(result) # Output: -5.0
Ensuring positive values:
result = math.copysign(-7, 4)
print(result) # Output: 7.0
Handling zero:
result = math.copysign(0, -2)
print(result) # Output: -0.0
Finance:
Example: Adjusting losses based on market conditions
If you want to apply the sign of the market direction (positive for gains, negative for losses) to a specific amount:
import math
loss = math.copysign(5000, -1) # Apply a negative sign to represent loss
print(loss) # Output: -5000
Physics:
Example: Applying direction to velocity or force
When calculating velocity in physics, if direction matters:
velocity = math.copysign(20, -1) # Negative velocity means moving in the opposite direction
print(velocity) # Output: -20
Example 1: Basic Usage
Demonstrates the basic functionality of `copysign()`.
