Mathematical Operators

• Visual Basic provides you with the following
  mathematical operators
• Addition
• - Subtraction
• Multiplication
• / Division
• \ Integer division
• Mod Return the integer from division
• Exponent
• String concatenation

Mathematical Functions

• Visual Basic provides the following mathematical
  functions
• Abs (n) absolute value of n in radians
• Atn(n) arc tangent of n in radians
• Cos(n) cosine of n in radians
• Exp(n) e raised to the power of n
• Rnd(n) random number generator
• Sgn(n) returns -1 if nlt0, 0 if n0, and 1 if n
  gt0

Mathematical Functions (Cont)

• Sin(n) sine of n in radians
• Sqr(n) square root of n
• Str(n) converts numeric value of n into a
  string
• Val(n) converts string (text) into a numeric
  value
• Tan(n) tangent of n in radians

5
Operator Precedence

• In a formula, how does the computer solve an
  equation?
• Visual Basic uses operator precedence in the
  following order
• () parenthesis
• exponent
• - negation
• / multiplication and division
• \ integer division
• Mod return the remainder
• - addition and subtraction

Operator Precedence (Cont)

• In the following example
• 532 14 (not 64)
