A Python tool for measuring and comparing whether sin(x) and cos(x) are implemented as standard (≤2 ULP guaranteed) or as approximate “fast-math” versions across multiple GPU backends (Vulkan, D3D12, ...

print("If you entered the value of x then you get answer in \n3sin(inverse)x, \n3cos(inverse)x, \n3tan(inverse)x") print(f"\n3sin(inv)x = {get_inverse_formula(A ...

from math import sin, cos, pi print(sin(pi/2)) # 1.0 print(cos(pi/2)) # 6.123233995736766e-17 The actual methods by which sin and cos are calculated are rather complicated (I’ll return to this in ...

This post begins a series on how sin and cos are calculated in the c language standard math library on a typical Linux system. Because Python floats are really c doubles, what I write here applies to ...
