Lame is a high-level interpreted language that makes hardware interaction obvious. The operators that are available reflect that.

Arithmetic

• + - Add

• - - Subtract / Negate

• * - Multiply

• / - Divide

• % - Modulus

Comparison

• == - Equals

• <> - Not equals

• > - Greater than

• >= - Greater than or equal to

• < - Less than

• <= - Less than or equal to

Location

Inside an object obj, anything can be referenced with ..

obj.CONSTANT

obj.variable

obj.function()

Address

The address of a symbol can be returned with @.

addr = @x

The value can be retrieved from an address with *.

y = *addr

Math Built-Ins

• sqrt(x) - Square root

• abs(x) - Absolute value

• max(x, y) - Maximum

• min(x, y) - Minimum

• rand(x) - Random
