copysign(): Copying Sign of One Number to Another

copysign(x, y)

print(math.copysign(3, -2))  # -3.0
print(math.copysign(-3, -2)) # -3.0
print(math.copysign(-3, 2))  # 3.0
print(math.copysign(3, 2))   # 3.0

import math

result = math.copysign(5, -3)
print(result)  # Output: -5.0

result = math.copysign(-7, 4)
print(result)  # Output: 7.0

result = math.copysign(0, -2)
print(result)  # Output: -0.0

import math

loss = math.copysign(5000, -1)  # Apply a negative sign to represent loss
print(loss)  # Output: -5000

velocity = math.copysign(20, -1)  # Negative velocity means moving in the opposite direction
print(velocity)  # Output: -20

Example 1: Basic Usage

import math

print(math.copysign(3, -5))  # Output: -3.0
print(math.copysign(-4, 2))  # Output: 4.0

Example 2: Copying Sign with Zero

print(math.copysign(0, -1))  # Output: -0.0
print(math.copysign(0, 1))   # Output: 0.0

Example 3: Adjusting Values in Scientific Calculations

values = [10, -20, 15, -25]
adjusted = [math.copysign(val, -1) for val in values]
print(adjusted)

[-10.0, -20.0, -15.0, -25.0]

Applications of copysign()

• Data Normalization: Standardize signs across datasets.
• Scientific Computing: Adjust values based on specific sign conditions.
• Financial Calculations: Control sign in calculations, such as debits and credits.
