Functions in Arithmetic Formulas
Function
Description
n sqrt(n)
Calculates the square root.
n fabs(n)
Finds absolute value of parameter.
n log(n)
Calculates the natural logarithm of parameter.
n log10(n)
Calculates the base-10 logarithm of parameter.
n exp(n)
Calculates the exponential value of parameter.
n pow(n1,n2)
Calculates n1 raised to power of n2.
n fmod(n1,n2)
Calculates the floating-point remainder n of n1/n2 such
that n1 = i * n2 + n, where i is integer and n has same
sign as n1, and the absolute value of n is less than the
absolute value of n2.
n sin(n)
Calculates the sine value of parameter.
n cos(n)
Calculates the cosine value of parameter.
n tan(n)
Calculates the tangent value of parameter.
n round(n)
Rounds an argument value to the nearest integer.
n floor(n)
Calculates the floor of a value. Returns a value
representing the largest integer that is less than or equal
to n.
n ceil(n)
Calculates the ceiling of a value. Returns a value
representing the smallest integer that is greater than or
equal to n.
n trunc(n)
Converts floating point n to integer by simply removing
any fractional part of parameter.
