Expression Functions -- Auto-Generated¶

Info

This page is auto-generated from the safe_eval() function in syntax.py at build time. It cannot go stale.

These functions and constants are available in variable expressions, calc, if, while, assert, check, and pyeval.

Type Conversions¶

Function	Description
`int(x)`	Convert to integer
`float(x)`	Convert to float
`str(x)`	Convert to string
`bool(x)`	Convert to boolean
`hex(x)`	Integer to hex string
`bin(x)`	Integer to binary string
`oct(x)`	Integer to octal string
`ord(c)`	Character to Unicode code point
`chr(n)`	Unicode code point to character

Function	Description
`sqrt(x)`	Square root
`log(x)`	Natural logarithm
`log2(x)`	Base-2 logarithm
`log10(x)`	Base-10 logarithm
`exp(x)`	e raised to power x
`ceil(x)`	Round up to nearest integer
`floor(x)`	Round down to nearest integer
`hypot(x, y)`	Euclidean distance: sqrt(xx + yy)

Function	Description
`sin(x)`	Sine (radians)
`cos(x)`	Cosine (radians)
`tan(x)`	Tangent (radians)
`asin(x)`	Inverse sine
`acos(x)`	Inverse cosine
`atan(x)`	Inverse tangent
`atan2(y, x)`	Two-argument inverse tangent
`degrees(x)`	Radians to degrees
`radians(x)`	Degrees to radians

Function	Description
`is_nan(x)`	True if x is NaN
`is_inf(x)`	True if x is infinite
`is_finite(x)`	True if x is finite (not NaN or inf)

Division by zero returns nan (not an error)
Attribute access (obj.attr) is not allowed
Unknown names are treated as string literals (e.g., status == passed compares against the string "passed")
^ is rewritten to ** -- use ^ for exponentiation, not bitwise XOR
