Advanced Math Instructions
Instruction Used To:
SIN Take the sine of a number and store the result in the destination. 211
COS Take the cosine of a number and store the result in the
destination.
TAN Take the tangent of a number and store the result in the
destination.
ASN Take the arc sine of a number and store the result(in radians) in
the destination.
ACS Take the arc cosine of a number and store the result (in radians)
in the destination.
ATN Take the arc tangent of a number and store the result (in radians)
in the destination.
DEG Convert radians (source) to degrees and store the result in the
destination.
RAD Convert degrees (source) to radians and store the result in the
destination.
LN Take the natural log of the value in the source and store it in the
destination.
LOG Take the log base 10 of the value in the source and store it in the
destination.
XPY Raise a value to a power and stores the result in the destination. 231
CPT Evaluate an expression and store the result in the destination.
Most math instructions use three parameters, Source A, Source B, and
Destination (additional parameters are described where applicable, later
in this chapter). The mathematical operation is performed using both
Source values. The result is stored in the Destination.
