Math#
Introduction#
Math includes both built-in Python functions and the full math
module, which is automatically available in VEXcode GO. These tools allow you to perform everything from basic arithmetic to advanced trigonometry, rounding, and logarithmic operations.
Use these functions and constants to calculate positions, angles, distances, and other numeric values for your robot. You can also convert between degrees and radians, evaluate expressions, and work with special values like infinity and NaN.
