The functions available in Touch Develop are:
abs
math ->
abs (x : Number) returns Number
returns the absolute value of input parameter x
basic.showNumber(math.abs(-7), 150)
clamp
math ->
clamp (min : Number, max : Number, value : Number) returns Number
limits a number to a range (between a min and max number); returns min
if value
is < min
; returns max
if value
is > max
; otherwise, returns value
.
basic.showNumber(td.clamp(5, 9, 12), 150)
max
math ->
max (x : Number, y : Number) returns Number
returns the larger of two input numbers (x
and y
)
basic.showNumber(Math.max(9, 7), 150)
min
math ->
min (x : Number, y : Number) returns Number
returns the smaller of two input numbers (x
and y
)
basic.showNumber(Math.min(9, 7), 150)
mod
math ->
mod (x : Number, y : Number) returns Number
returns the integer modulus/remainder resulting from the division of the number x
by the number y
basic.showNumber(math.mod(9, 7), 150)
pow
math ->
pow (base : Number, exp : Number) returns Number
returns the value of the number base
raised to the power exp
basic.showNumber(math.pow(3, 3), 150)
