divide — GTM Variable Template for Number

VARIABLES › NUMBER

divide CORE Number

Direct (.tpl) Apply (.tpl)

Divides the numerator by the denominator. Returns undefined for division by zero.

When to Use This

Number Operations

Arithmetic, rounding, clamping, and mathematical transformations on numeric values.

Read-Only Try Live

Numerator

💾 The number to divide (dividend).

Supported formats:
  ✓ Number
  ✓ String

Denominator

💾 The number to divide by (divisor).

Supported formats:
  ✓ Number
  ✓ String

Input Setup

Input Function (optional)

⚙️ Optional pre-processing function applied to the input before internal logic (e.g., convert object to string, normalize case). Internal transformations such as case handling will still apply afterward.

Result Handling

Output Function (optional)

⚙️ Optional function to apply to the result before returning it (e.g., str => str + ' €', val => val !== undefined for boolean conversion). Useful for chaining transformations on the output.

🔗 Result Handling — Chain Variables

Chain apply-mode variables to the output. Each variable receives the result of the previous one.
