![]() Decimal powers rounds at eighth decimal place. ![]() For example, returns 2.688E43 for 100.Ĭan construct unit valid equation that can go invalid "pow(3.0 d12)". When entering an angle, the default unit is degrees. Use "ul" to indicate a unitless value: 2 mm + 1 mm * (3ul^2ul). The following expression is in error because the system expects default units: In expressions, assign a unit to each numerical value in the expression. For example:ĭoes not evaluate to 4 square meters, but rather means 2 square meters. Therefore, the power operator applies to a unit before it applies to an adjacent numeric value. Units are evaluated before the arithmetic portion of an expression. Including units and specifying which units are unitless results in the correct evaluation: 2 mm + ((3 ul) ^ 3 ul ) * 1 mm.ĭoes not allow assignment of units to an expression. Because the units are ambiguous, the expression is shown in red to indicate an error: The results are in error because dissimilar units cannot be added: 2 mm + (3 mm)^3ul is evaluated as 2 mm + 27 mm^3. ![]() The edit box assigns default units to all terms unless a unit is specified. If no syntax errors are found, the characters are shown in black.Įxponents are applied to units as well as the expression. If an expression contains syntax errors, they are shown in red. Algebraic operators + addition - subtraction floating point modulo multiplication / division power ( expression delimiter ) expression delimiter delimiter for multiargument functions Note: To avoid conflict with floating point decimal delimiter ('.' vs ',') in. The following operators are supported in parameters and dimension edit boxes. An expression is evaluated according to the algebraic order of operations and default unit values. Use these operators to create expressions. If you do not specify units in an edit box, terms and coefficients are assigned default units. The edit box uses the units specified in the default document properties.
