#### 9.37.7 Math Builtins

The following built-in functions may be used to generate a floating-point value. All return a floating-point value except ‘`$cvi`’, ‘`$int`’, and ‘`$sgn`’, which return an integer value.

`$acos(`expr`)`
  Returns the floating point arccosine of expr.

`$asin(`expr`)`
  Returns the floating point arcsine of expr.

`$atan(`expr`)`
  Returns the floating point arctangent of expr.

`$atan2(`expr1`,`expr2`)`
  Returns the floating point arctangent of expr1 / expr2.

`$ceil(`expr`)`
  Returns the smallest integer not less than expr as floating point.

`$cosh(`expr`)`
  Returns the floating point hyperbolic cosine of expr.

`$cos(`expr`)`
  Returns the floating point cosine of expr.

`$cvf(`expr`)`
  Returns the integer value expr converted to floating-point.

`$cvi(`expr`)`
  Returns the floating point value expr converted to integer.

`$exp(`expr`)`
  Returns the floating point value e ^ expr.

`$fabs(`expr`)`
  Returns the floating point absolute value of expr.

`$floor(`expr`)`
  Returns the largest integer that is not greater than expr as floating point.

`$fmod(`expr1`,`expr2`)`
  Returns the floating point remainder of expr1 / expr2.

`$int(`expr`)`
  Returns 1 if expr evaluates to an integer, zero otherwise.

`$ldexp(`expr1`,`expr2`)`
  Returns the floating point value expr1 * 2 ^ expr2.

`$log10(`expr`)`
  Returns the base 10 logarithm of expr.

`$log(`expr`)`
  Returns the natural logarithm of expr.

`$max(`expr1`,`expr2`)`
  Returns the floating point maximum of expr1 and expr2.

`$min(`expr1`,`expr2`)`
  Returns the floating point minimum of expr1 and expr2.

`$pow(`expr1`,`expr2`)`
  Returns the floating point value expr1 ^ expr2.

`$round(`expr`)`
  Returns the nearest integer to expr as a floating point number.

`$sgn(`expr`)`
  Returns -1, 0, or 1 based on the sign of expr.

`$sin(`expr`)`
  Returns the floating point sine of expr.

`$sinh(`expr`)`
  Returns the floating point hyperbolic sine of expr.

`$sqrt(`expr`)`
  Returns the floating point square root of expr.

`$tan(`expr`)`
  Returns the floating point tangent of expr.

`$tanh(`expr`)`
  Returns the floating point hyperbolic tangent of expr.

`$trunc(`expr`)`
  Returns the integer value of expr truncated towards zero as floating point.
