Formula: Syntax

QuickField formula is an expression composed of the following elements:

• numeric constants

  integer (Ex: 123)

  fixed-point (Ex: 123.45  123.  0.123  .123)

  floating-point (Ex: 1e12  5.39e+8  0.1E-12  .2E+2)

• arithmetic operators

  + addition (Ex: 2+2)

  - subtraction (Ex: 3-5)

  * multiplication (Ex: 1.23*0.12)

  / division (Ex: 1E5/0.01)

  ^ raising to a power (Ex: 3.14^2)

• unary operators

  + sign retaining (Ex: +180)

  - sign change (Ex: -180)

• embedded functions (see detailed description in Formula: Functions)
