Arithmetic functions
ndsl.stencils offers the following arithmetic functions as building blocks:
dim(a, b)
Calculates a - b, camped to 0, i.e. max(a - b, 0).
sign(a, b)
Defines a_sign_b as the absolute value of a, and checks if b is positive or negative, assigning the analogous sign value to a_sign_b. a_sign_b is returned.
Parameters:
| Name | Type | Description | Default |
