sqrt — Returns a square root value.

**sqrt**(x) (no rate restriction)

where the argument within the parentheses may be an expression. Value converters perform arithmetic translation from units of one kind to units of another. The result can then be a term in a further expression.

Here is an example of the sqrt opcode. It uses the file *sqrt.csd*.

**Example 812. Example of the sqrt opcode.**

See the sections *Real-time Audio* and *Command Line Flags* for more information on using command line flags.

Its output should include lines like these:

square root of left channel = 1.000000 square root of left channel = 0.948688 square root of left channel = 0.894437 square root of left channel = 0.836676 square root of left channel = 0.774620 square root of left channel = 0.707139 square root of left channel = 0.632499 square root of left channel = 0.547781 square root of left channel = 0.447295 square root of left channel = 0.316242
