Float Literals

You can use float literals and perform arithmetic operations with them. Example:

<span>{{ 1.534 + 2.5 }}</span>

Precision limit (IEEE 754)

Floating-point numbers have ~15-17 digit precision. For example, 1234567890.1234567890 rounds to 1234567890.1234567.

Large numbers as strings

Keep large numbers as strings if you need exact precision.

Division follows the operand types

Float division like 4.0 / 2.0 returns a float. Integer division like 4 / 2 returns an integer.

Follows IEEE 754 like Go

Overflow produces +Inf or -Inf, values too small to represent underflow to 0.0, and invalid operations like +Inf - +Inf produce NaN. These special values are printed as +Inf, -Inf, and NaN.

Non-finite floats become null in JSON

+Inf, -Inf, and NaN are serialized as null.
