Type Conversions (str, int, float, bool)

Type Conversions

The str(), int(), float(), and bool() built-in functions convert values between types. Explicit conversion is required when mixing types in formulas — Precision Bridge does not implicitly coerce types.

str()

Converts any value to its string representation.

str(42)                    # '42'
str(3.14)                  # '3.14'
str(True)                  # 'True'
str(None)                  # 'None'
str([priority])            # Converts field to string

Common use: Concatenating numeric fields with text.

'Priority: ' + str([priority])

int()

Converts a value to an integer. Truncates decimal portions (does not round).

int('42')                  # 42
int(3.9)                   # 3 (truncated, not rounded)
int(True)                  # 1
int(False)                 # 0
int([score])               # Converts field to integer

Common use: Converting string fields that contain numeric values.

int([priority]) if [priority] is not None else 0

Note: int() raises an error if the string is not a valid integer. Always check for None first.

float()

Converts a value to a floating-point number.

float('3.14')              # 3.14
float(42)                  # 42.0
float([temperature])       # Converts field to float

Common use: Numeric calculations that need decimal precision.

round(float([price]) * 1.1, 2)

bool()

Converts a value to a boolean. The following values are falsy (convert to False):

• None, False, 0, 0.0, '' (empty string), [] (empty list), {} (empty dict), set() (empty set)

Everything else is truthy (converts to True).

bool(0)                    # False
bool(1)                    # True
bool('')                   # False
bool('hello')              # True
bool(None)                 # False
bool([])                   # False

Common use: Checking if a field has a meaningful value.

'Yes' if bool([active]) else 'No'

Handling None Safely

Always guard against None before converting, since int(None) and float(None) raise errors:

int([field]) if [field] is not None else 0
float([field]) if [field] is not None else 0.0
str([field]) if [field] is not None else ''

Or use the if_null() function:

int(if_null([field], '0'))
