2-10 E2 User's Manual Supplement: Flexible Combiner
Description
Returns the square root of value. Value must not be
negative, or else a Bad Result error will occur.
Returns value to the power of power. This is the same
as the "^" operator.
Returns the base-10 logarithm of value.
Returns e (2.72) raised to the power of value.
Returns natural logarithm of value.
Description
Converts value from radians to degrees.
Converts value from degrees to radians
Returns the sine of value.
Returns the cosine of value.
Returns the tangent of value.
Returns the arcsine of value. Value must be con-
strained to between -1 and 1, otherwise a Bad Result
math error will occur.
Returns the arccosine of value. Value must be con-
strained to between -1 and 1, otherwise a Bad Result
math error will occur.
Returns the arctangent of value.
Same as the SIN function, except value is assumed to
be radians.
Same as the COS function, except value is assumed to
be radians.
