# Math and Trigonometry Functions¶

ABS Returns the absolute value of a number.
ACOS Returns the arccosine of a number in radians in the range 0 to pi.
ACOSH Returns the inverse hyperbolic cosine of a number.
ASIN Returns the arcsine of a number in radians in the range -pi/2 to pi/2.
ASINH Returns the inverse hyperbolic sine of a number.
ATAN Returns the arctangent of a number in radians in the range -pi/2 to pi/2
ATAN2 Returns the four-quadrant arctangent of the specified x- and y- coordinates in radians between -pi and pi excluding -pi. A positive result represents a counterclockwise angle from the x-axis, a negative result represents a clockwise angle.

LOG10 Returns the base-10 logarithm of a number.
MDETERM Returns the matrix determinant of an array.
MINVERSE Returns the inverse matrix for the matrix stored in an array.
MMULT Returns the matrix product of two arrays. The result is an array with the same number of rows as array1 and the same number of columns as array2.
MOD Returns the remainder of a division operation (modulus).
ODD Returns a number rounded up away from zero to the nearest odd integer.
PI Returns the approximate number 3.14159265358979, the mathematical constant pi, accurate to 15 digits.
