CSE 110: Programming Language I Afroza Sultana UB 1230

Math Class Very useful. Provides many methods in a pre-built class. The following are available in the Math class Trigonometry functions (input in radian instead of in degree): sin, cos, tan, acos, atan, asin

Exponent Methods exp – raise e to a power sqrt – returns the square root pow – raise a number to a power log – natural log of a number

Rounding in Math Class ceil – round up to nearest integer floor – round down to nearest integer

Helpful Math random – Returns a random number greater than or equal to 0.0 and less than 1.0 abs – return absolute value of a number min – return minimum of two numbers max – return max of two numbers
