# Floating Point Expressions

Some helpful information on using floating point expressions in the Scenario Builder application is given as follows.

- An expression starts with = sign, e.g. in "a=b" assignment block, =2+3 in the value field would result in 6. If you omit the equal sign, the result would be "2+3"
- Either the point or exponent can be used (e.g.,
*2.00*or*2E00*or*20E-1*or*.2E1*).

- The four arithmetic operations and parentheses, including nested ones, are supported.

- A mix of floats and integers produces a floating expression.

- Division by zero produces an error in the log; the operation result is undefined.
