<p></p> <p><b>New page</b></p><div>== Menu / Icon ==<br /> <br /> This tool is accessible via the &#039;Edit &gt; Scalar fields &gt; Arithmetic&#039; menu or the [[Image:CcSfArithmetic.png]] icon in the upper main toolbar.<br /> <br /> == Description ==<br /> <br /> This tool allows to:<br /> * perform standard arithmetic operations between two scalar fields of the same cloud (+,-,*,/)<br /> * or apply mathematical functions to a single scalar field<br /> <br /> [[Image:Cc_sf_arithmetic_dialog.jpg|frame|center|Edit &gt; Scalar Fields &gt; Arithmetic dialog]]<br /> <br /> <br /> Other than the standard operations (that can be applied to a second scalar field or a constant value), the other supported mathematical functions are:<br /> * square root<br /> * power of 2<br /> * power of 3<br /> * EXP (exponential)<br /> * LOG (natural log)<br /> * LOG10 (base 10 log)<br /> * COS (radians)<br /> * SIN (radians)<br /> * TAN(radians)<br /> * ACOS<br /> * ASIN<br /> * ATAN<br /> * Integer part<br /> * Inverse (1/x)<br /> <br /> <br /> Since version 2.6.3:<br /> * the user can select a constant value instead of a secondary scalar field for the standard operations (+,-,*,/)<br /> * the user can choose to update the first scalar field directly (&#039;in place&#039;). Otherwise a new scalar field will be created. Anyway the source scalar fields are never deleted.</div>
